Question

find the area of the circular foot ball ground of diameter 800 m​

Answer 1

Answer:

502857.14 m^2

Explanation:

Area of circle = πr^2

Radius = 800/2 = 400 m

= 22/7 * 400 * 400

= 3520000/7

= 502857.14 m^2

Answer 2

Answer:

Hello mate✌✌✌

Given,

d = 800m

r = d/2 = 800/2 = 400m

Now,

Area of football ground = $\pi {r}^{2} \\ \frac{22}{7} \times 400 \times 400 \\ \frac{22}{7} \times 16000 \\ 50285.71 \: {m}^{2}$

Hope it helps✌✌✌
