Joan incorrectly finds the volume of a cone with a radius of 4 cm and a height of 6 cm. She thinks the volume is 301.44 cm3. Her
Stolb23 [73]

Answer:

Correct volume = 100.48 cm³

Step-by-step explanation:

The formula for finding the volume of a cone is:

V = πr²(h/3)

r - Radius

h - Height

V - Volume

To find the correct volume of the cone, we just need to input the measurements into their respective places in the formula and solve. Your work should look similar to the following:

V = πr²(h/3)

V = π(4)²(6/3)

V = π(16)(6/3)

V = π(16)(2)

V = π(32)

V = 100.48 cm³

(You can use the work shown above to find Joan's mistake in her work.)

~Hope this Helps!~
