Question

find the area of a circle of diameter 8.4 m​

Answer 1

$<b>hey mate here your answer Diameter = 8.4 Radius =$
$\frac{8.4}{2} = 4.2$

Area of circle =$\pi \: r ^{2}$

$\frac{22}{7} \times 4.2 \times 4.2$

$55.44 \: cm ^{2}$

Answer 2

Heya❤

$area \: of \: the \: circle \: = \pi {r}^{2}$

Diameter=8.4m

Radius=4.2m

Hence,

$area =\pi \times {4.2}^{2}$

Area= 22/7 × 17.64

$area = 55.44 {m}^{2}$

Hope it helps you
