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

A(x~~,~~\stackrel{y}{6})\qquad \qquad \begin{array}{llll} \stackrel{\textit{since we know that}}{y=-\cfrac{3}{7}x+3}\implies 6=-\cfrac{3}{7}x+3\implies 3=-\cfrac{3x}{7} \\\\\\ 21=-3x\implies \cfrac{21}{-3}=x\implies -7=x \end{array} \\\\[-0.35em] ~\dotfill\\\\ B(\stackrel{x}{9}~~,~~y)\qquad \qquad \begin{array}{llll} \stackrel{\textit{since we know that}}{y=-\cfrac{3}{7}x+3}\implies y=-\cfrac{3}{7}(9)+3\implies y=-\cfrac{27}{7}+3 \\\\\\ y=\cfrac{-27+21}{7}\implies y=-\cfrac{6}{7} \end{array}
