Find the volume of a can of chicken broth that had a diameter of 7.5cm and a height of 11cm. round 5o the neatest tenth

Cans are normally cylinders

Vcylinder=hpir^2

h=11

d/2=r

7.5/2=3.75=r

V=11pi3.75^2

V=11pi14.0625

V=154.6875pi

aprox pi=3.141592 and multiply

V=485.96

round tenth

486.0 cm^3

Okay. So. For the top and bottom of the can:

Take the radius, which is half of the diameter, so its 3.75. Then you find the area which is 3.14 (pie) x3.75 squared. So the equation is : 3.14x (3.75) 3.75=44.15625

Then multiply by two because there is a top and bottom. So,

88.3125.

Then find the area of the middle of the can.

Which is pie times the diameter times the height.

So that is:

3.14 x 7.5 x 11=259.05

So then you add those two together.

259.05 + 88.3125 = 347.3625,

Or 347.36 cm cubed.
