Question

Find the area of a circular park of diameter 30m

Answer 1

$given \: diameter \: of \: circular \: park \: = 30m \\ \\ = > 2 \times radius = 30 \\ \\ = > radius = 15m \\ \\ area \: of \: circle = \pi \times r {}^{2} \\ \\ = \frac{22 \times 225}{7} = \frac{4950}{7}$

Answer 2

Explanation:

givendiameterofcircularpark=30m

=>2×radius=30

=>radius=15m

areaofcircle=π×r
