The formula V = pi×r^2×h gives the volume of a cylinder with radlus r and height h. Find the volume of a cylinder with radius (x + 4) cm and height 5 cm Write your answer in standard form.​

Answer:

V = 15.7*x^2 + 125.6*x + 251.2     I'd use this as an answer, but it depends how you have been told to treat pi. This answer is also possible.

V = 5*pi*x^2 + 40*pi*x + 80*pi

I can't really tell you which one to use.

Step-by-step explanation:

Givens

V=pi*r^2 * h

pi = 3.14

r = (x + 4)

h = 5

Solution

V = pi * (x + 4)^2 * 5

V = pi * (x^2 + 8x + 16)*5

V = pi * (5x^2 + 40x + 80)     Now the question is what to do with pi.

V = 5*pi*x^2 + 40*pi*x + 80*pi

That one possible answer. The other is to give pi a value

V = 15.7*x^2 + 125.6*x + 251.2

Answer:

Solution given:

V=πr²h

when radius and height is given

If

height [h]=5cm

radius [r]=(x+4)cm

Now

new Volume=π(x+4)²×5=5π(x²+8x+16)=

5πx²+40πx+80 is your answer
