To print it with a decimal component, you need to format how its displayed, not change how its stored and used, this doesn't make a difference what the type of the number is. The numbers on the left half of the line like 13 or 11 are closer to 10, so they round to 10. Notice that the arc of a circle is just the part of the circumference enclosed by the endpoints of both radians. Step 3: Write the final answer that ends at the tenths place. We are ready to solve for the area of circle p. Exercise 1 Find the area of circle p. In fact, this shape is not a at all, which means that it doesn't have vertices or sides.

For this storage shed one end will be left open, except for the gable. For those exercises, we can apply the area of sectors formula, which is where A represents area, x represents the degree measure of the central angle, and r is the radius. Areas of Circles The area of a circle is equal to the product of pi? Here are some more examples. Where C represents the circumference and R represents the radius. Because circles don't have sharp edges, their areas in square units will almost never come out to an even number, so we will just round areas to the hundredths place.

Remember, we did not necessarily round up or down, but to the ten that is nearest to 254. If we know that the circle is split up into a certain amount of congruent areas, we can just put the corresponding factor into our area formula. Because all of the radians of a circle are equal, we know that two of them make up the diameter of a circle. However, when we round up the nine becomes a ten. Find the tenths place and figure out whether to round up or down.

Also 12 is nearest to 10 than 20. The area shaded in blue is the open end. We have In order to get rid of the square, we need to take the square root of both sides: We know that the radius of circle g is approximately 23 feet, but we haven't solved for the variable x. In these cases, we will need a way to calculate these parts of circles called sectors. How to estimate 2534 to the nearest 10? Exercise 2 Find the value of x if the area of circle g is approximately 1661 square feet. Our rounded answer will stop at the tenths place. Instead, it will stay the same.

For instance, if we have a circle that is split up into four equal sections, and we want to find the area of one of those sections, our area formula would be Because one-fourth of the circle is shaded, we just multiply the area formula of circle c by a factor of Â¼ to find the area of the circle sector. The area of the circle is, therefore, 254. You can round a number up or down to the nearest 2, 4, 5, 10, 50, etc. This number is already rounded to the nearest tenth, so you don't need to do anything here. Let's learn how to use the area formula for circles. For now, just underline this digit.

Step 1: Locate the tenths place. This means that we round it up from 5 to 6. In other words, if we are given the diameter of a circle, we know that half of the diameter is equal to the radius, which we can plug into our area formula. Therefore, we round the 5 up to a 6. Sometimes it is advantageous to express a value in round numbers. Enter two positive numbers or two negative numbers. This formula essentially does the same as what we've done in the previous example because it just converts the degree measure of the interior angle into an equivalent fraction.

Step 1: Locate the tenths place. Many situations will call for you to round decimals to the nearest tenth to make the number easier to work with. Article Summary To round to the nearest tenth, write down the number with a decimal point, and find the tenths place directly to the right of the decimal. If the number to the right is 4 or less, you will leave the tenths place alone. Byju's Rounding to the Nearest Tenth Calculator is a tool which makes calculations very simple and interesting. Your textbook might be trying to trick you. Thinking Further Now, let's go back and analyze the relationship between the degree measure of the central angle and the portion of the circle that was shaded.

Step 2: Look to the right of the tenths place and use the number to determine if you will round up or stay the same. We just need to subtract 7 from both sides of the equation, and we get So, the value of x is approximately 16. We know that 56 is closer to 60, so 0. Therefore, we know that where d is the length of the diameter of a circle and r is the length of the radius. The tenth position is the position to the right of the decimal point: 214. Multiply out the constants on the right side to get:. Circles have degree measures of 360Â°.

Round off to the nearest tens: i 362 The given number is 362. Just remove any digits in the hundredths place and further to the right. In other cases, we may be given the measure of the angle at the radius of a circle, called the central angle.
