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.

An oblique cylinder has a radius of 10 units and slant length of 26 units. What is the volume of the cylinder
marysya [2.9K]
The formula of the volume of an oblique cylinder is V = \pir²h where \pi is 3.14, r is the radius of the circular base of the cylinder and h is the height of the cylinder. You are given a slant length and radius of 26 and 10 units. You can get the height by using pythagorean theorem c²=a²+b².

c²=a²+b²
26² = 10² + b²
b = 24

V = \pir²h
V = \pi(10)²(24)
V = 7,540 units³
