Find the missing dimension of the cylinder. Round your answer to the nearest whole number.

Volume = 250 ft³
h ≈ ___ ft?

3ft (to nearest whole number)

Step-by-step explanation:

Volume of a cylinder = πr²h

Where r is the radius

h is the height

Given volume = 250ft³

Since are not given the radius, let's assume the radius of the cylinder to be 5ft

Substituting this values in the formula to get the height

250 = π(5)²h

250 = 25×3.14×h

250 = 78.5h

h = 250/78.5

h = 3.19

h is approximately 3ft (to nearest whole number)

complete question:

Find the missing dimension of the cylinder. Round your answer to the nearest whole number.

volume = 250 ft³

diameter = 8 ft

h = ___ ft

h ≈ 5 ft

Step-by-step explanation:

The volume of the cylinder is given, likewise the diameter of the cylinder . The volume a cylinder can be represented as

volume = πr²h

where

r = radius

h = height

we were given the diameter, so we find the radius from it diameter .

r = d/2

d = 8 ft

volume = 250 ft³

r = 8/2 = 4 ft

volume = πr²h

250 = π × 4² × h

250 = 16πh

250 = 16 × 22/7 × h

250 = 352h/7

cross multiply

250 × 7 = 352h

1750  = 352 h

divide both sides by 352

h = 1750/352

h = 4.97159090909

h ≈ 5 ft

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
