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

Answer:

8163 sq.m

Step-by-step explanation:

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

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

$a = \pi \times (51 \div 2) {}^{2} + 51 \times 120$

$a = 2043 + 6120$

$a = 8163$

answer is to the nearest square meter
