Question

a tennis ball is of diameter 7.0cm. what is the volume in cubic meter and cubic centimeter​

Answer 1

Answer:

Hey mate here is your answer ready

Explanation:

Tennis ball is a sphere in shape.

diameter = 7 cm

radius = 7/2 = 3.5 cm

Volume=4/3πr²

Volume=4/3*3.142*3.5³

Volume=179.618cm³

Answer 2

GIVEN:

The diameter of a tennis ball = 7 cm

Radius of the tennis ball = 7/2cm

TO FIND:

Volume of the ball in cubic meters and centimetres.

SOLUTION:

The ball is in the shape of a sphere. So, we should find the volume of sphere.

We know that,

Volume of Sphere = 4/3πr²

==> 4/3 × 22/7 × 7/2 × 7/2 × 7/2

==> 1/3 × 11 × 7 × 7 ×

==> 11 × 49 × 1/3

==> 539/3

==> 179.66 cm³

Convert 179.66cm³ into m³

179.66 * 10^-6 m = 0.00017966m³

Therefore, the volume of ball is 179.66cm³.
