Question

The diameter of a circle is 20m. Find its area in terms of pie(urgent)

Answer 1

Answer:

$= 100\pi {m}^{2}$

Step-by-step explanation:

$d = 2r \\ 20 =2 r \\ \frac{20}{2} = \frac{2r}{2} \\ r = 10$

$area = \pi {r}^{2} \\ = \pi \times 10 \times 10 \\ = 100\pi {m}^{2}$

hope this helps

Answer 2

Answer:

100 pie m^2

$solution \\ diameter = 20 \: m \\ radius = \frac{20}{2} = 10 \: m \\ area \: = \pi \: {r}^{2} \\ \: \: \: \: \: \: \: \: \: \: \: = \pi \times {10}^{2} \\ \: \: \: \: \: \: \: \: \: \: = \pi \times 100 \\ \: \: \: \: \: = 100\pi \: {m}^{2} \\ hope \: it \: helps....$
