I need some assistance on this

1650

Step-by-step explanation:

The shape is a pyramid on top of a prism.

Volume of a pyramid is V = ⅓ Ah, where A is the area of the base and h is the height of the pyramid.

Volume of a prism is V = Ah, where A is the area of the base and h is the height of the prism.

The base of both shapes is a right triangle.  The area is:

A = ½ bh

A = ½ (22) (10)

A = 110

The height of the prism is 6.  The height of the pyramid is 33 − 6 = 27.  The total volume is:

V = (110) (6) + ⅓ (110) (27)

V = 1650

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
