Answer:

$V=97.6\ in^3$

Step-by-step explanation:

step 1

Find the volume of the cylinder

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=4/2=2\ in$ ---> the radius is half the diameter

$h=8\ in$

substitute

$V=\pi (2)^{2}(8)\\\\V=32\pi\ in^3$

step 2

Find the volume of the cone

The volume of the cone is equal to

$V=\frac{1}{3}\pi r^{2} h$

we have

$r=2\ in$ ---> the radius is the same that the radius of the cylinder

$h=0.70\ in$

substitute

$V=\frac{1}{3}\pi (2)^{2} (0.70)\\\\V=0.93\pi\ in^3$

step 3

Find the volume of the plastic object

we know that

The volume of the plastic object is equal to the volume of the cylinder minus the volume of the cone

$V=32\pi-0.93\pi=31.07\pi\ in^3$

assume

$\pi=3.1416$

$V=31.07(3.1416)=97.6\ in^3$

If a ball rotates 110 degrees in 8 seconds, how many degrees does it rotate in 32 seconds?

Vlad1618 [11]

Well 32 divided by 8 would be 4 so... 32 x 4 would be 128 so 128 times. If it’s not correct I’m really sorry.

Help me, I don't understand this problem

Crank

Read some notes on reflection. If it asks to reflect it on the x-axis youre going to reflect it either on the bottom or top plane. If it asks to reflect on y-axis youre going to reflect it on either the left or right plane.

Pat shows that 16 1/2= the square root of 16. What is one possible way pat could have shown this correctly?

kifflom [539]

<h3>Answer: Choice C</h3>

The base 16 is the same as 4*4.

From there, the rule $(a*b)^c = a^c*b^c$ is used to get $(4*4)^{1/2} = 4^{1/2}*4^{1/2}$

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is $a^b*a^c = a^{b+c}$ which only works if the bases are both the same.
