Best Answer

pi*r2 = 28.26

Divide both sides by pi:

r2 = 8.995437384

Square root both sides:

radius = 2.999239468

diameter = 2*radius:

diameter = 5.998478935 or 6 centimeters to the nearest cm.

What is the area of a circle with a diameter of 60 ft?

2826 square feet


Area of a circle is 2826 sq. cm, find its radius (Take π = 3.14)?

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 radius is 30 inches.


What is the radius of a circle with an area of 2826?

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)

Find radius of cylinder if height equals 36cm and volume equals 2826?

volume = p*radius2*height make the radius the subject of the formula: radius = the square root of (volume/pi*height) radius = the square root of (2826/pi*36) radius = 4.998732446cm So the radius is 5cm to the nearest cm.
