20
Explanation:
20 + 4 = 24. Therefore 24-20=4
Volume id proportional to the cube of the dimensions.
The volume of the larger room is 10 x (2 cubed)
= 80 cubic metres.
l = 7.5 * 10^-6
3l = 3* (7.5* 10^-6)
= 22.5 * 10^-6
000022.5 * 10^-6
move the decimal 6 places to the left
.0000225 meters
Answer: .0000225 meters
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.
