Find the surface area of a cylinder with a base diameter of 8ft and a height of 6ft. write your answer in terms of pi, and be sure to include the correct unit.

Given that diameter of the base of the cylinder = 8 ft

Given that height of the cylinder = 6 ft

We have to find the surface area of the cylinder in terms of pi.

So we need to use formula of surface area of the cylinder which is

where h= height = 6

r= radius = diameter/2 = 8/2 = 4

Now plug these values into above formula

Hence final answer is

square ft

80

Step-by-step explanation:

We are given a cylinder with a base diameter of 8 feet and a height of 6 feet and we supposed to find its surface area.

We know the formula of surface area of cylinder

where to get:

Therefore, the surface area of the given cylinder is 80.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

a reflection across the x axis and a 90 degree rotation left and right.
