Question

if rhe area of circle is 154cm square then its perimeter is

Answer 1

Answer:

Perimeter of circle is 44 cm.

Step-by-step explanation:

πr^2 = area of circle

πr^2 = 154 cm^2

r^2 = 154 x 7/22

r^2 = 7 x 7

r = 7 cm

Perimeter of circle= 2πr

Perimeter of circle = 2 x 22/7 x 7 cm

Perimeter of circle = 44 cm

Answer 2

Area of circle 2 Pai R

2×22/7×154
2×22×22
44×22
968
area of perimeter 2(l+b)
2(968+154)
2(1122)
