Answer:

Explanation:

We khow that the area of a cercle is :

A= r²*π where r is the radius

A= 153.86 in²

so : r² = 153.86/π = 48.97 ≈ 49

then r = 7

so the diameter is 14 in

Answer:

d = 13.9965 in

Explanation:

Area of a Circle Formula: A = πr²

diameter = 2r

Step 1: Plug in known variables

153.86 = πr²

Step 2: Solve for r

153.86/π = r²

r² = 48.9752

r = √48.9752

r = 6.99823

Step 3: Find d

d = 2(6.99823)

d = 13.9965
