The volume of this cylinder is 1,909.92384 cubic millimeters. What is the radius? Use n=3.14 and round your answer to the neares
klemol [59]

Remember that the volume of a cylinder is

\begin{gathered} V=\pi\cdot r^2\cdot h \\  \end{gathered}

so we have that

r=\sqrt[]{\frac{V}{\pi\cdot h}}=\sqrt[]{\frac{1909.92384}{3.14\cdot6.6}}=\sqrt[]{92.12}=9.6

so the radius is 9.6 milimeters

The vertices of a triangle are P(–8, 6), Q(1, –3), and R(–6, –3). Name the vertices of
xz_007 [3.2K]
The refrection of a point or set of points across the line y = x will result in a point or set of points whose coordinates are the interchange of the x-value and the y-value of the original point or set of points.

Given that the vertices of a triangle are P(-8, 6), Q(1, -3) and R(-6, -3), the vertices of the triangle formed by the refrection Ry=x<span>(ΔPQR) are P'(6, -8), Q'(-3, 1) and R'(-3, -6).</span>
