Part 2: describe the shape of your cross section of a slice of banana at 45° angle to a space draw picture of the sheep. Part 3:

xenn [34]

Answer:

Part 2:

The shape of a banana cut in 45° angle is that of a curve that is closed with the appearance of a flattened circle or an oval similar to an ellipse therefore having two focal points

The drawing of the angle cross section of a cylinder representing the banana is attached

Part 3:

When the banana is cut in half, perpendicular to the base of the banana, the shape formed is circular withe the center of the banana being about the same location as the center of the circle

The drawing of the perpendicular cross section of a cylinder representing the banana is

Gold in the form of solid cylinders will be molded into solid blocks. Each cylinder has a diameter of 6.18 cm and a height of 6

nordsb [41]

First we need to find out the volume of one cylinder. We already know the volume of the block of gold is 360cm3

V = Pie * radius squared* height.

Pie is 3.142

radius is 6.18/2 = 3.09 cm

height is 6cm

V = 3.142 * 3.09 * 3.09 * 6

V = 180cm3

Now we divide the volume of this cylinder with the volume of block of gold.

360/180 = 2

So it will take 2 cylinders to mold one block of gold.

Find the area of each shaded region. give your answer as a completely simplified exact value in terms of pi. (no approximates)

frez [133]

Answer:

52 $\pi$

Step-by-step explanation:

We see that the radius of the big circle is 8m, and we see that the it is also the diameter of the second smallest circle. We also see that this diameter is split into two equal parts, and since the entire length is 8, each part will be 4. So what we need to do is find the area of each circle.

First we can start by finding the area of the smallest circle. The radius of this circle will be 4/2, 2. So the area of this circle will be $\pi$ $r^{2}$ , and in this case 4 $\pi$ .

Then we need to find the area of the bigger shaded portion, which will be the area of the big circle, minus the area of the smaller white circle.

First, lets find the are of the big circle, which again, will be $\pi$ $r^{2}$ . This time, we plug in a radius of 8, and we get 64 $\pi$ .

Next we find the area of the smaller white circle, again $\pi$ $r^{2}$ . We use a radius of 4 this time, giving us an area of 16 $\pi$ .

Now we subtract the two values we found previously to find the area of the just the bigger shaded portion. That value will be 64 $\pi$ -16 $\pi$ , which is 48 $\pi$

We then take 48 $\pi$ , and we add the small shaded portion, which had an area of 4 $\pi$ , and we add them, giving us a total of 52 $\pi$ .

Hope this helped.
