Answer:

Step-by-step explanation:

Find h when v = 20 and r = 3

Putting values in the formula

20 = (3.14)(3)2h

20 = (3.14)(9)h

20 = 28.26h

20/28.26 = h

R when v = 100 and h = 5

100 = (3.14)r2(5)

100/5 = 3.14r2

20 = 3.14r2

20/3.14 = r2

6.36 = r2

Square root on both sides

2.52 = r

Answer:

Part A: It would be a rectangle because the top face is a triangle and since the cut is parallel it would be the same shape.

Part B: It would be a rectangle because the faces that are perpendicular to the base of the rectangle are rectangles so the cut would be the same shape.

Note: The perpendicular sides look like squares, but you do not want to assume that they are squares unless it is stated.

The volume of a rectangular prism can be found by multiplying the three side lengths. A bookcase in the shape of a rectangular p
Vesna [10]

Answer:

(b³+11b²+24)ft³

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Given the dimension

Length = b+8 ft

Width = b ft

Height = (b+3)ft

Volume of the rectangular prism = b(b+8)(b+3)

Volume of the rectangular prism = b(b^2+3b+8b+24)

Volume of the rectangular prism = b(b^2+11b+24)

Volume of the rectangular prism = b(b^2)+b(11b)+1(24)

Volume of the rectangular prism = b^3+11b^2+24

Hence the Volume of the rectangular prism is (b³+11b²+24)ft³
