The volume of a spherical sculpture is 256 ft³. Rhianna wants to estimate the surface area of the sculpture. To do the estimate, she approximates π using 3 in both the surface area and volume formulas for a sphere. Using this method, what value does she get for the approximate surface area of the sculpture?

192

Step-by-step explanation:

Given that

Volume of spherical sculpture = 256 ft³

is used as 3.

To find:

Surface area of sculpture = ?

Solution:

First of all, let us learn about the formula for Volume and Surface Area of Sphere:

1.

2.

Given volume is 256 ft³.

Now, let us put r = 4 in the formula of Surface Area to find the value of Surface Area:

So, approximate surface area of sculpture is 192 .
