The base of a basketball goal has the shape of a rectangular pyramid. the base of the goal must be filled with sand so the goal does not fall down. the base of the pyramid is 4.5 feet long and 4 feet wide. the height of the pyramid is 2.5 feet. how much sand will be needed to fill the base of the basketball goal?

a. 7.1 ft^3
b. 15 ft^3
c. 22.5 ft^3
d. 45 ft^3

  B.  15 ft^3

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

  V = (1/3)Bh

where B represents the area of the base, and h represents the height.

The base is apparently a rectangle, so its area is the product of its length and width:

  B = L·W = (4.5 ft)(4 ft) = 18 ft^2

Then the volume is ...

  V = (1/3)(18 ft^2)(2.5 ft) = 15 ft^3

15 cubic feet of sand will be needed to fill the base.

step-by-step explanation:

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
