Radius = 10.997211381 units of measurement

If i do understand what u are saying then the equation is area=pi(radius^2) In this case it is 28=3.14(r^2) the radius is equal to 3 so the diameter is about 6. If i do understand what u are saying then the equation is area=pi(radius^2) In this case it is 28=3.14(r^2) the radius is equal to 3 (approx.) so the diameter is about 6.

It is 14 cm.

It is: 2*radius = square root of (616/pi) = 28 inches to the nearest integer

Radius = 10.997211381 units of measurement

Using 3.14 as Pi the area of circle is: 2461.76

approx 2463m squared

Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared

Find the circumference of a circle with radius 5 ft.Area of a circle. The area of a circle of radius r is given by the polynomial πr2. Use 3.14 as an approximation for π.

Area = pi*r2 where r is the radius. So Area = 28 sq inches gives radius = 2.985 inches and then, diameter = 2*radius = 5.971 inches.

area_of_circle = {pi} x radius2 diameter = 2 x radius So work out the radius from the area and double it: 28 sq in = {pi} x radius2 => radius = sqrt(28 / {pi}) in ~= 3 in => diameter = 2 x radius ~= 6 in

If this circle is 28ft then: Area of a circle = pi time r2 A diameter of 28 feet means a radius of 14 feet Area = pi times 196 or 615.75 square feet

28"

Diameter = 28 m => radius = 28/2 m = 14 metres. Then, area = pi*r2 = 615.75 sq metres.
