Question

The area of a circle is 153. 86 square meters. What is the diameter of the circle? use 3. 14 for π.

Answer 1

Answer:

14

Explanation:

A=pi × r²

153.86 = 3.14 × r²

Divide both sides of the equation by 3.14

it becomes:

r²=153.86÷3.14

r²=49

taking the square root for both sides of the equation

r = 7

and

diameter = 2 × radius

diameter = 2 × 7 = 14
