Question

A circle has a diameter of 41 centimeters. Which equation can be used to find the radius of this circle? ​

Answer 1

Equation to find radius = Diameter divided by 2

Area is 1319.585

Explanation:

Diameter = 41 cm

Radius = 41÷2 = 20.5cm

Area = πr^2

Area = 3.14×(20.5)^2

Area = 3.14×420.25

Area = 1319.585cm^2
