Answer:

15/16

Step-by-step explanation:

In khan academy, you treat pi as a variable. I just ignore it usually tho.

For the cone you get 15 and for the cylinder you get 16 so 15/16

The radius of the planet Uranus is approximately 4 times the size of the radius of Earth. What does this tell you about the volu

Sonja [21]

Answer:

Step-by-step explanation:

Earth volume is approximately V = (4/3)πr³, and

Uranus volume is approximately V = (4/3)π(4r)³, or (4/3)π*64*r³

Comparing these two results, we see that the volume of Uranus is approximately 64 times greater than the volyume of Earth.

Two semicircles are attached to the sides of a rectangle as shown.

melomori [17]

Answer:

$157\ in^{2}$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle plus the area of two semicircles

The area of rectangle is equal to

$A=14*5=70\ in^{2}$

The area of the small semicircle is equal to

$A=\pi r^{2} /2$

$r=5/2=2.5\ in$ -----> radius is half the diameter

substitute

$A=(3.14)(2.5^{2})/2=9.8125 in^{2}$

The area of the larger semicircle is equal to

$A=\pi r^{2} /2$

$r=14/2=7\ in$ -----> radius is half the diameter

substitute

$A=(3.14)(7^{2})/2=76.93\ in^{2}$

The area of the figure is equal to

$70+9.8125+76.93=156.7425=157\ in^{2}$
