What is the volume of a cylinder, in cubic centimeters, with a height of 8 centimeters
Arisa [49]

Answer:

1608.5 cm³

Step-by-step explanation:

Use the cylinder volume formula, V = \pir²h

If the diameter is 16 cm, then the radius is 8 cm.

Plug in the radius and height into the formula, and solve:

V = \pir²h

V = \pi(8)²(8)

V = \pi(64)(8)

V = 1608.5

So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³

The length of a rectangle is 3 more than the width fine the length if the perimeter is 98 inches
german

Answer - Width 23

Length - 26



W = Width


L + 3 = Length



Perimeter = 2L = 2W


98 = 2(W + 3) + 2W


98 = 2W + 6 + 2W


98 = 4W + 6


92 = 4W


W = 92/4


W = 23


Width is 23 inches

Length is 3 more -- 23 + 3 = 26



We can double check our work:


26 + 26 + 23 + 23 = 98 Inches



Best of luck,
