A cylinder has a radius of 50 ft and a height of 18 ft. What is the exact surface area of the cylinder?
Sati [7]
The formula of the total surface area of the cylinder would be: Base area+ surface area along the circumference.

To find an exact value,we would also have to save 兀and not turn it in other approximate values.

The base area would be:
兀r^2
=兀(50)^2
=2500兀 ft^2

The surface area along the circumferecen would be:
2兀r(base circumference) x height
=2兀50×18
=250兀×18
=4500兀 ft^2

Adding them up,we would then find the total surface area:

4500兀+2500兀
=7000丌 ft^2

Thus,the answer is 7000 丌 ft^2.

Hope it helps!

Jen wrote ten times as many pages of a school report as tom. They wrote 396 pages altogether. How many pages did each student wr
Lunna [17]

Let pages written by Tom for a school report = x

Pages written by Jen for school report= 10 x

Pages written by Tom + Pages written by Jen = 396

→ x  + 10 x = 396

→ 11 x =396

Dividing both sides by 11, we get

→ x =36,

Pages wrote by Tom= 36 pages

Pages wrote by Jen = 36 × 10=360 pages
