Ineed ! it is urgent. how is the volume of a hemisphere related to its circumscribed cylinder? explain

A cylinder that circumscribers a hemisphere will share a base with the hemisphere. If the base has radius , then the volume of the hemisphere is

A cylinder with radius and height has volume , but a cylinder that circumscribes a hemisphere will have a height equal to the radius of the hemisphere, so . Such a cylinder would have a volume of

So, the volume of the hemisphere is of the volume of the cylinder.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
