What is the volume of a cylinder with a height of 10 inches and diameter of 4

125.663706144 inches^3

Step-by-step explanation:

Volume of a cylinder is:

v=πr^2h

First, we need to find the radius, since we have the diameter

r=d/2

r=4/2

r=2

Substitute 2 in for r, and 10 in for in the volume formula

v=πr^2h

v=π2^2*10

v=π4*10

v=π40

v=125.663706144

125.663706144 inches^3

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

the answer is 3/2 and for decimal: 1.5
