The radius of the wheel on a car is 21 inches. if the wheel is revolving at 202 revolutions per minute, what is the linear speed of the car in miles per hour

25.2398 miles per hour.

Step-by-step explanation:

Circumference of the wheel = 2π(21) = 131.947 inches. Convert to miles. 131.947/12 = 10.9956 ft. 10.9956/5280 = 0.002082 miles. Multiply by 202 to get miles per minute. 0.002082*202 =.420664 miles per minute. Multiply by 60 to get miles per hour. 60*.420664 = 25.2398 miles per hour.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
