Question

Area of circle = 154 square metre . find its perimeter and radius​

Answer 1

Step-by-step explanation:

Area of circle = πr²

$\implies 154 = πr^{2}$

$\implies 154 = \frac {22}{7} \times r^{2}$

$\implies r^{2} = 49$

$\implies \boxed{r = 7}$

Perimeter of circle = 2πr

$\implies2 \times \frac{22}{7} \times 7$

$\implies \boxed{Perimeter of circle = 44}$

Answer 2

area of circle is equal to one fifty four

area of circle formula is equal to pie r2

as pie is equal to 22/7 × r^2=154

r^2=154×7/22

r^2=49

$r = \sqrt{49}$

r=7

perimeter of circle is equal to

2πr i.e is equal to 2×22/7×7

308/7

44
