28.26/3.14=9 square root =3
Check: 3x3x3.14=9x3.14=28.26
The area of a circle is 153.86cm².find the radius of the circle
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle with a radius of 7 cm is: 153.9 cm2
The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.
Radius is 30 inches.
The radius is 30 inches.
We apply the formula for the area of a circle to determine the radius of the circle: Area is equal to π * radius^2. Now that we know the area is 2826 square centimeters and that π is roughly 3.14, we can rewrite the formula to find the radius: 3.14 * radius^2 = 2826 Dividing 3.14 across both sides: radius^2 = 3.14 / 2826 radius^2 is around 900.63. To find the radius, take the square root of both sides: radius ≈ √900.63 radius approximately 30.04 centimeters
the formula for the area of a circle is pi times r squared (sorry this website does not work today for presenting this better) so 2826 = pi times r squared so dividing through on both sides bi pi gives you: 2826 divided by pi = r squared so r is the square root of (2826/ pi) 2826/pi = 899.5437384 so r is the square root of 899.5437384 = 29.99239468 r = 29.99 (to 2 decimal places)
