Question

What’s the surface area of a bowling ball if the radius is 2.5

Answer 1

Answer:

Therefore,

$\textrm{Surface Area of Bowling ball}=78.5\ unit^{2}$

Step-by-step explanation:

Given:

Shape is Sphere,

Radius = r = 2.5 unit,

pi = 3.14

To Find:

Surface area of a bowling ball = ?

Solution:

We know Surface Area of Sphere is given as

$\textrm{Surface Area of Sphere}=4\pi r^{2}$

Substituting the values we get

$\textrm{Surface Area of Bowling ball}=4\times 3.14\times (2.5)^{2}$

$\textrm{Surface Area of Bowling ball}=78.5\ unit^{2}$

Therefore,

$\textrm{Surface Area of Bowling ball}=78.5\ unit^{2}$
