Difference between Sphere and Circle Surface Area of Sphere

Find the surface area of ball which has the following radius

A) Radius of 87 cm ?
B) Radius of 68 cm ?
C) Radius of 88 cm ?
D) Radius of 53 cm ?
E) Radius of 63 cm ?

A) Radius of 87 cm ?

The given things are -
Radius = 87 cm
Value of Π = 3.142

Surface Area of Sphere = 4 X Π X Radius²
Surface Area of Sphere = 4 X 3.142 X (87)²
Surface Area of Sphere = 12.568 X 7569
Surface Area of Sphere = 95127.192 cm

B) Radius of 68 cm ?

The given things are -
Radius = 68 cm
Value of Π = 3.142

Surface Area of Sphere = 4 X Π X Radius²
Surface Area of Sphere = 4 X 3.142 X (68)²
Surface Area of Sphere = 12.568 X 4624
Surface Area of Sphere = 58114.432 cm

C) Radius of 88 cm ?

The given things are -
Radius = 88 cm
Value of Π = 3.142

Surface Area of Sphere = 4 X Π X Radius²
Surface Area of Sphere = 4 X 3.142 X (88)²
Surface Area of Sphere = 12.568 X 7744
Surface Area of Sphere = 97326.592 cm

The given things are -
Radius = 53 cm
Value of Π = 3.142

Surface Area of Sphere = 4 X Π X Radius²
Surface Area of Sphere = 4 X 3.142 X (53)²
Surface Area of Sphere = 12.568 X 2809
Surface Area of Sphere = 35303.512 cm

E) Radius of 63 cm ?

The given things are -
Radius = 63 cm
Value of Π = 3.142

Surface Area of Sphere = 4 X Π X Radius²
