Question

Given the area of a circle to be 10 inches^2 what is the radius and the diameter the circumference

Answer 1

Radius = 1.78 inches

Diameter = 3.56 inches

Circumference = 11.18 inches

Explanation:

Area of circle = 10 inches square

`\pi r^2 = 10\\r^2 = (10)/(3.14)\\r^2 = 3.18\\√(r^2)=√(3.18)\\r=1.78`

Radius = 1.78 inches

Diameter = 2r = 2(1.78) = 3.56 inches

Circumference = 2πr = 2*3.14*1.78 = 11.18 inches
