Izzie has a muffin tin that holds 12 muffin cups. Each cup is cylindrical with a diameter of 3 and a height of 3.5 inches. Izzie has 544.28 cubic inches of batter. How many muffins did she bake?

Answer 1

Volume of the muffin tin.

r=1.5

h=3.5

V=$\pi r^2h\\$

$V=3.142×(1.5)^2×(3 .5)\\ V=24.74~ cubic~inches\\ \text{then for the total number of muffins she bake, that is }\\ \frac{544.28}{24.74}=22.\\ \text{she bakes 22 muffins}$
