Question

the diagram represents a sports ground. the bends are semicircle. calculate the area of the sports ground. give your answer correct to the nearest square metre

Answer 1

8163 sq.m

Explanation:

as the two bends are semi circles, together they make a full circle,

area of the ground = area of the circle + middle section

`a = \pi * (51 / 2) {}^(2) + 51 * 120`

`a = 2043 + 6120`

`a = 8163`

answer is to the nearest square meter
