Question

A bakery is making cupcakes using a cylindrical mold. The cupcake mold has a diameter of 5.5 centimeters and is 2 centimeters tall. Which of the following shows a correct method to calculate the amount of cupcake batter needed to fill the mold all the way to the top? Use 3.14 for π.

V = (3.14)(5.5)2(2)
V = (3.14)(2)2(5.5)
V = (3.14)(2.75)2(2)
V = (3.14)(2)2(2.75)

Answer 1

V = (3.14)(2.75)²(2)

This is because the formula for finding the volume of a cylinder is V = πr²h, where r is the radius of the base, and h is the height of the cylinder. In this case, the diameter of the mold is 5.5 cm, so the radius is half of that, 2.75 cm. The height of the mold is 2 cm. Plugging these values into the formula gives us the answer above.
