A garden is in the shape of a semicircle with a diameter of 40m. What is the area of the garden? Use 3.14 as an approximation for IT
A 5,024 m
B 2,152 m²
C 1,256 m2
D 628 m²

D) 628 m^2

Explanation:

Let's find the area of the full circle first. The radius is 20 meters, since that's half of the diameter 40. So we have r = 20.

We'll use pi = 3.14 as an approximation

A = area of full circle

A = pi*r^2

A = 3.14*20^2

A = 1256

This is the area of a full circle, but we want half of that because we want the area of a semicircle instead. Since your teacher put 1256 for choice C in there, it seems like that is a trick answer.

We'll divide 1256 over 2 to get 1256/2 = 628 square meters as the final answer, which is choice D.

We can abbreviate "square meters" into "m^2".

9 x 8 divided by (5-3)=36
