Find the volume of a cylinder with a diameter of 10 inches and height of 20in
weqwewe [10]

Answer:

V = 500 pi in^3

or approximately 1570 in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is  the radius and h is the height

The diameter is 10. so the radius is d/2 = 10/2 =5

V = pi (5)^2 * 20

V = pi *25*20

V = 500 pi in^3

We can approximate pi by 3.14

V = 3.14 * 500

V = 1570 in ^3

Lenox ironed 1/4 of the shirts over the weekend. She plans to split the remainder of the work equally over the next 5 evenings.
MrMuchimi

3/20, or 0.15 of the shirts each evening


1 - 1/4 = 3/4

(3/4) / 5 = (3/4) / (5/1) = (3/4) x (1/5) = 3/20 = 0.15

D = V • t    ...    displacement = velocity • time 
d = [(s – 4) ⁄ (s² – 9s + 20)] • [(s – 5) ⁄ 4]    ...    rearrange terms 
d = (s – 4) • (s – 5)   ⁄   [4(s² – 9s + 20)]    ...    factor denominator 
d = (s – 4) • (s – 5)   ⁄   [4(s – 4) • (s – 5)]
