Question

find the area of a circle of diameter 8.4m

Answer 1

diameter = 8.4m
radius = d/2 = 8.4/2 = 4.2
Area of a circle = 22/7* 4.2*4.2= 55.44 m2

Answer 2

hey mate here your answer

area of circle =
$\pi \times {r}^{2}$
so radius is = d/2
so , r=4.2

by putting in equation

22/7×4.2×4.2
= 55.44 m2
