Question

find the area of circle whose radius is 10.5?​

Answer 1

Answer:

area of circle = πr^2

= 22÷7×(10.5)^2

= 3.14 × 110.25

= 346.185 answer

Answer 2

$\huge\underline\bold{ANSWER:-}$

Given information,

Radius of the circle is 10.5 cm

We know that,

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

$so \: area \: of \: the \: circle \: = \pi \times 10.5 \: cm {}^{2}$

We know that 22/7 is an approximation used to denote pi.

$area \: of \: the \: circle \: = \frac{22}{7} \times 10.5 = 33 \: cm {}^{2}$
