Answer:

volume=558.9

Step-by-step explanation:

find the volume of the cone and the hemisphere and add them together

<u>cone:</u>

Vcone=\pi r^{2} \frac{h}{3} \\\\V=\pi (5.3)^2(\frac{8.4}{3} )\\V=\pi (28.09)(2.8)\\V=247.09\pi \\V=247.1

<u>hemisphere:</u>

<u></u>Vhemisphere=\frac{2\pi r^3}{3} \\V=\frac{2\pi (5.3)^3}{3} \\V=\frac{2\pi (148.877)}{3} \\V=\frac{297.754\pi }{3} \\V=\frac{935.421}{3}\\ V=311.8

<u>add the volumes together:</u>

<u></u>Vol=247.1+311.8\\Vol=558.9

(05.01 MC) choose the systems of equations which matches the following graph​
topjm [15]

Answer:

a

Step-by-step explanation:

x+2y=-10

-x       -x

2y=-10-x

y=(1/2)x-5

This is one of the lines and reduces the options to a or c.

3x-y=12

-3x    -3x

-y=12-3x

y=3x-12

This is the line with the positive slope and since both lines match, the answer is a.
