Find the volume of the cylinder having a radius of 4 inches and whose height is 10 inches.
question 7 options:
160π in.3
40π in.3
16π in.3
160π in.2

Step-by-step explanation:

Use the formula for the volume of a cylinder with circular base of radius R:

Where R is the radius of the circular base (in our case 4 inches)

and H is the cylinder's height (in our case 10 inches)

Therefore:

6 mile/hour

Explanation :

Let the speed of walking of James = x mile/hour

speed of jogging = 2x mile/hour

9/2x + 1.5/x = 2

= > (9 + 3)/2x = 2

= > 12 = 4x

= > x = 3

Average speed of walking = 3 mile/hour

Average speed of jogging = 2 * 3 = 6 mile/hour
