A pipe has a diameter of 2.5 inches and a length of 15 inches. The plumber wants to wrap the pipe in tape. What is the surface area of the pipe? He also wants to know how much water can flow through his pipe at one time. To the nearest tenth, what is the volume of the pipe?

117.8 in²

73.6in³

Step-by-step explanation:

the pipe is in the shape of a open cylinder. the surface area = πdl

π = 3.14

l = length

d = diameter

volume of a cylinder = nr^2h

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

n = 22/7

r = radius = 2.5/2 = 1.25

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

3.14 x (1.25^2) x 15 = 73.6

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

correct answer:

a + bi

c. (3,2,6) is the answer.
