A crystal ball has a radius of 4 inches. What is the approximate volume of the crystal ball? Use 3.14 for Pi. Round to the nearest tenth. Recall the formula Sphere Volume = four-thirds pi r cubed. 50.2 cubic inches 67.0 cubic inches 267.9 cubic inches 2,143.6 cubic inches

The volume of the crystal ball is  267.9 inches³

Step-by-step explanation:

To find the approximate volume of the crystal ball with a radius of 4 inches , we will follow the steps below;

first write the formula for calculating the volume of a sphere

v= πr³

where r is the radius of the crystal ball  and v is the volume of the crystal ball

from the question given, radius = 4 inches  and   π = 3.14

we can now proceed to insert the values into the formula

v= πr³

  = × 3.14 ×4³

  = × 3.14 ×64

   =803.84/3

   ≈267.9

v≈ 267.9 inches³

The volume of the crystal ball is  267.9 inches³

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
