The formula for the area of a circle is pi times the radius squared, so if the radius is 6 inches, that is pi times 36 square inches. Pi is approximately 3.1415, which gives us an area of 113.094 square inches. If that is not exact enough, pi has been worked out to thousands of decimal places, and can be easily looked up on Google.
3850m is the area of the a circle whose radius of 7meaters
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
A circle with a radius of 11m has an area of ~380.13 m2
A circle with a radius of 13 units has an area of 530.93 square units.
area = π × tradius² → area = π × 6² = 36π.
Area of circle = πr2 Exact area = π(14)2 = 196π cm2
The area of a circle is equal to pi times the radius squared. A 12 foot radius circle would have an area of exactly 144 pi square feet.
Exact area of the circle: 9*pi inches
A circle with a radius of 11.64 meters has an area of 425.653131998 square meters.
Exact area of the circle: 9*pi inches
pi x square of radius
Oh, dude, you want the area of a circle with a radius of 31 cm? Like, okay, so the formula for the area of a circle is πr^2. So, just plug in 31 for the radius, square it, multiply by π, and you get the area. It's around 3017.77 square centimeters, but who's counting, right?
Area of a circle is pi x r2 Area of a circle having a a radius of 12 units = 3.1416 x 144 units2 = 452.389 units2
There is no way to find the exact area of a circle. The formula for the area is Pi times the radius squared. But Pi is an irrational number -- that is, no matter how many numbers you write it out to, you could always write it further. Since there is no exact value of Pi there can be no exact value of the area based on the diameter. The radius is half that of a diameter. Therefore, if you know the diameter you know the radius. In this case the radius is 3cm and the area of the circle = pi * 32 So the answer is roughly
168.56 square inches
The area is exactly (324 pi) square feet.
