Replace a with 4 and b with -12

Each of the following integrals represents the volume of either a hemisphere or a cone, and the variable of integration measures
iris [78.8K]

Answer:

1. cone

   radius, height = 2, 10

  volume = 13.33

2. hemisphere

   radius=  14

  volume = 1829.33

Step-by-step explanation:

The  region  described  has  a  radius r=2−y/5, therefore, the volume is a cone

radius, height = 2, 10

volume =

\int\limits^{10}_0 {\pi ( 2-\frac{y}{5} )^2} \, dy \\=

= 13.33

2. The  region  ∫14 0 π(196 - h^2) dh   has  a  radius 196 - h^2,  so the volume is a hemisphere

radius  = 14

volume

=\int\limits^{14}_0 {\pi (196 - h^{2}  )} \, dh

=\pi (196h- \frac{h^3}{3}) |^{14}_0

=1829.33

Help pls 2x - 2 = -18
nexus9112 [7]

Answer:

x=-8

Step-by-step explanation:

We are solving for the variable, x, so let us <u>isolate</u> all terms of x. Let us start by moving the numerical value 2 to the right side, thereby <u>isolating</u> the term 2x on the left:

2x= -18+2

2x=-16

So close! Let us divide both sides by 2 now:

x= -8
