Question

find the radius of a circle of area 2200/ 7 dm? ans 10 dm .​

Answer 1

Answer:

πr²=2200/7

r²=100

r=10

(π is taken as 22/7 dear)

Answer 2

Step-by-step explanation:

Area= π × r²

$\frac{2200}{7} = \frac{22}{7} \times {r}^{2}$

$\frac{2200 \times 7}{22 \times 7} = {r}^{2}$

$\sqrt{100} = r$

$10 = r$
