Otrada [13]

Answer:

565cm³

Step-by-step explanation:

If Kelly eats the salsa until it is 6cm high, then she ate, in height, 11cm-6cm=5cm of salsa. The volume of the salsa she ate is in the shape of a cylinder, and the formula for calculating the volume of a cylinder is πr^2h. Since we have the values for r (radius) and h (height), we can solve for the volume.

V=πr^2h

V=π(6cm)^2(5cm)

V=180πcm³

This is equal to about 565cm³.
