Question

A semicircular flower bed has a diameter of 3 metres.

Answer 1

R=1.5m
area of a semicircle=($\pi r^{2}$)/2
therefore the area = 3.535

Answer 2

area of a full circle = PI*r^2

r = 3/2 =1.5

using 3.14 for pi

3.14 *1.5^ = 7.065 square meters

 a semicircle is half of a circle so now divide7.065 by2

7.065/2 = 3.5325 square meters, round answer as needed
