Answer 2

Question

Find the area of the following circles, given that (Take π =22/7)

(b) diameter = 49 m

Solution

Diameter= 49m

radius = d/2= 49/2

radius= 24.5

area of circle=

$\pi \: {r}^{2} \\ \frac{22}{7} \times {24.5}^{2} \\ \frac{22}{7 } \times 24.5 \times 24.5 \\ 22 \times 3.5 \times 24.5 \\ 77 \times 24.5 \\ 1886.5m$
