Using first the customary ruler and then the metric ruler, measure the length of the side of the wooden block. Remember to estimate to one place value beyond the rulers’ gradations.
Answer:
87.965
Step-by-step explanation:
surface area of a cylinder,
2πr²+2πrh (where r = radius, h = height)
given, h = 5, r = 2
so,
2πr²+2πrh
= 2π×2²+2π×2×5
= 8π+20π
= 28π
= 87.9645943..
= 87.965 (rounded to the nearest thousand)
Answer:
12 inches
Step-by-step explanation:
The storage bin is in the shape of a rectangular prism.
Its volume is 5400 cubic inches and its base area is 450 square inches.
The volume of a rectangular prism is given as:
V = L * W * H
where L = length
W = width
H = height
The product of the length and width gives the base area of the rectangular prism:
A = L * W
This implies that:
V = A * H
=> 5400 = 450 * H
H = 5400 / 450
H = 12 inches
The height of the bin is 12 inches.
