Question

radius of a sphere whose surface area is 154 cm”​

Answer 1

Answer:

Area of sphere : 4 x 22/7 x r x r = 154

: 88/7 x r x r = 154

: 88r x r = 154 x 7

: r x r = 1078/88

: r x r = 12.25

: r = 3.5

Step-by-step explanation:

Hey dude ur radius measure is 3.5 cm

Answer 2

Answer:

radius = 7/2 cm

Step-by-step explanation:

surface area = 154cm ^2

4πr^2 = 154

r^2 = 154×7/22×4

r^2 = 49/4

r = 7/2cm
