What is the volume of this traffic cone with a diameter of 20 inches and a height of 36 inches?

volume of a cone =  3770 inches³

Step-by-step explanation:

to find the volume of a traffic cone whose diameter = 20inchhes

height of the cone = 36 inches

Recall that the fomular for finding the volume of a cone = 1/3 πr²h

note the radius was not given , to find the radius

radius = 1/2 × Diameter

radius = 20/2 inches

radius = 10inches

volume of a cone = 1/3 πr²h

volume of a cone = 1/3 × 22/7 × ( 10)² × 36

volume of a cone =  1/3 × 3.142 × 100 × 36

volume of a cone = 1/3 × 3.142 × 3600

volume of a cone = 11311.2/3

volume of a cone =  3770.4 inches³

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the correct answer is 5
