Question

find the area of circle,whose diameter is 14cm

Answer 1

if d=14 then r=7.
area=22/7×7^2
=22/7×49
=22×7
=154centimetresquare

Answer 2

Answer:

Area of the circle (A) = 154 cm²

Explanation:

Given diameter of a circle (d)=14 cm

We know that,

$\boxed{Area\: of\: the\: circle\: (A)= \pi\frac{d^{2}}{4}}$

$A = \frac{22}{7}\times\frac{(14)^{2}}{4}$

$\implies A = \frac{22\times14\times14}{7\times4}$

After cancellation, we get

$\implies A = 22\times7$

$\implies A = 154 \: cm^{2}$
