Question

find the area of circle having : 1. radius is 10 cm 2. diameter is 56

Answer 1

1.
$\pi {r}^{2}$
r=10cm
$\frac{22}{7} \times 10 \times 10$
$= \frac{2200}{7} {cm}^{2}$
2.
$\pi {r}^{2}$
$r = \frac{56}{2 } = 28cm$
$\frac{22}{7 } \times 28 \times 28 \\ = \frac{17248}{7} = 2464 {cm}^{2}$

Answer 2

Answer:

hi friend !!!!

Step-by-step explanation:

the answer for the first  question :

given that ,r=10 cm

w.k.t , area of the circle = πr²

by applying the given data ,

area of the circle = 22/7 ×10 ×10

                             =3.14
