Answer:
A 1759 sq. units
Step-by-step explanation:
to find the surface area of a closed cylinder the formula is
2πr² + πdh
r = radius = 10
d = diameter = 10 + 10 = 20
2 x 3.14 x 10² + 3.14 x 20 x 18
628.3 + 1130.94 = 1759.24
ans = 1759
108 divided by 3 equals 36.
I got this answer by multiplying 3 and 36, which equaled 108. Then I figured out that 108 divided by 3 equals 36!
Answer:
21.01 cubic metres
Step-by-step explanation:
We have to find the value of 1 cubic foot and then convert to cubic metre.
1 foot = 0.3048 m
1 cubic foot =
= 0.02832 cubic metre
A volume of 742 cubic foot will therefore be:
742 * 0.02832 = 21.01 cubic metres
The volume in cubic metres is 21.01 cubic metres
Answer:
Average change in temperature is - 2.8 Fahrenheit per hour.
Step-by-step explanation:
Average change in temperature is the change in temperature divided by the time taken for the change.
Change in temperature = (-11.2) F- 0 F
= -11.2 F
Time taken for the change in temperature = 10 pm - 6 pm
= 4 hours
Average change in temperature = Change in temperature / time taken for the change
= 
= - 2.8 Fahrenheit per hour
