A cylindrical can of soup has a diameter of 7 cm and a height of 10 cm. How much soup is in the can, in terms of π?

Natasha2012 [34]

Answer:

B) 122.5π cm3

Step-by-step explanation:

Volume of a cylinder = $\pi r^{2} h$

r= radius , but we are given diameter or 7cm, radius = diameter/2 =7/2 = 3.5cm

h= height, given as 10cm

$\pi = constant$

Next, plug in the numbers into the formula;

$=\pi *3.5^{2} *10\\ \\ =\pi *12.25 *10\\ \\ =122.5\pi$

Therefore, the volume of soup in the can is 122.5 $\pi cm^{3}$
