Question

the surface area of the sphere is 50. 24 cm find its radius ​

Answer 1

Answer:

2 cm

Step-by-step explanation:

Given :

Surface area of sphere = 50.24 cm

We know :

Surface area of sphere = 4 π r²

Let the radius be r cm

50.24 = 4 × π × r²

50.24 / 3.14 = 4 r²

16 = 4 r²

r² = 4

r = ± 2

Since length cannot be negative.

Hence , radius of sphere is 2 cm

Answer 2

Answer:

Step-by-step:

Surface area of sphere = 3πr^2

50.24 = 3 x 3.14 x r^2

50.24 = 9.42 x r^2

r^2 = 5.33

r = 2.309 cm
