Can somebody help me with #8?
Black_prince [1.1K]
The answer is about 27oz. and this is how you answer it.
<span>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.
