Can somebody help me with #8?

The answer is about 27oz. and this is how you answer it. pi(d/2)^2 * h = V 3.14(3.6in./2)^2 * 5.9in. = 3.14(1.8in.)^2 * 5.9in. = 3.14 * 3.24 * 5.9in. ~
10.17in. * 5.9in. ~ 60in.^2 and 1in.^2 = 0.45oz. so 60 * 0.45oz. = 27oz. that is with rounding to the nearest hundredth.

It's asking for volume, so it would be pi x r^2 x h So it would be the volume (60.02424) divided by .45 which is 133 (rounded)

To find the inside radius of the coffee mug, we calculate its volume using the given mass of 375 g, which translates to 375 cm³. By applying the cylinder volume formula, we solved for the radius and found it to be approximately 3.98 cm. This radius corresponds to the height of 7.50 cm that the coffee fills the mug.
