Answer:
8
3
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 3207
Radius, r
Height, = 5
320π = π * 5 * r²
320 = * 5 * r²
320 = 5 * r²
r² = 320/ 5
r² = 64
r = 8 m
The lateral surface area of a cube is
LSA = 4s²
Where s = edge length
36 = 4s²
s² = 36/4
s² = 9
s =. sqrt(9)
s = 3
Answer:
2 2/35 hours
Step-by-step explanation:
In 1 hour, the total amount of the house that is painted is ...
1/8 + 1/4 + 1/9 = 35/72 . . . of a house
We need to multiply the time (1 hour) by 72/35 to find the number of hours required for one entire house:
72/35(1 h) = 2 2/35 h
It would take them 2 2/35 hours to paint the house working together.
The most important information that needs to be kept in mind is the conversion from square foot to square inches. Other important information's are already given in the question.
1 square foot = 144 square inches
Now
Number of glasses required to cover 1 square foot = 8
Then
The number of glasses required to cover 144 square inches = 8
So
The number of glasses
required to cover 864 square inches = (8/144) * 864
= 8 * 6
= 48
So 48 pieces of glass are required to make a window that is 864 square inches. I hope the procedure is clear enough for you to understand.
