When you convert each type of ribbon to a bigger fraction, you get 32/6 feet of silver ribbon by multiplying the denominator by the whole number then adding the numerator. you also get 16/6 feet of gold ribbon. 32-16=16 so Gina has 16 more feet of silver ribbon than gold

The volume of a cylinder is given by the formula V= πr^2h, where r is the radius of the cylinder and h is the height. Suppose a
11111nata11111 [884]

we know that

The volume of a cylinder is given by the formula

V=\pi r^{2} h

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

r=x+8\\ h=2x+3

Substitute the values in the formula above

V=\pi*(x+8)^{2}*(2x+3)

V=\pi*(x^{2}+16x+64)*(2x+3) \\ V=\pi *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=\pi *(2x^{3} +35x^{2} +176x+192)

therefore

the answer is

The volume of the can is equal to

V=\pi *(2x^{3} +35x^{2} +176x+192) units ^{3}

Pls help with this volume wiestion
Zielflug [23.3K]

Answer:

15833.6269741 cm^3.But we can make it 15,833.63 cm^3 rounded to the nearest hundredth.

Step-by-step explanation:

so let’s solve this using the following formula -> V=\pi r^2h.

So if the height is 25 and the radius is 12 them we can plug those numbers into the formula.

\pi (12)^2(35).

So let’s start by doing 12 squared which is 144 then 144*35 which is 5040.

And now 5040*pi which is 15833.6269741 cm^3.But we can make it 15,833.63 cm^3 rounded to the nearest hundredth.

Id you ant to check if my answer is correct look at the image below.
