Question

What is the area when the diameter is 94cm

Answer 1

A ≈ 6,939.8 cm²

Explanation:

Given : " the diameter is 94cm "

d = 94

Radius is r = d/2 = 94/2 = 47 cm

Area of a circle is

A= π·r²

A = π·47² ≈ 6,939.8 cm²

Answer 2

see below

Explanation:

Area = pi r^2 r = radius

diamter = 94 then radius = 94/2 = 47 cm

area = pi (47)^2 = 2209 pi or 6939.78 cm^2
