Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π

for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more

therefore answer is 36π = 113.1 inches

Find the volume and round to the nearest tenth as needed
monitta

Answer: 1962.4 cubic mm

Step-by-step explanation:

The volume of the larger cone is V=\frac{1}{3}(\pi)(10^{2})(20)=\frac{2000\pi}{3}

The volume of the smaller cone is V=\frac{1}{3}(\pi)(3^{2})(14)=42\pi.

So, the volume is \frac{2000\pi}{3}-42\pi \approx \boxed{1962.4}

If Ryuk eats 7 apples for every 50 names Light writes in the death note, how many apples will he have eaten after Light writes 5
alex41 [277]

Answer:

70 apples

Step-by-step explanation:

We can use a ratio to solve

7 apples        x apples

--------------  = -------------

50 name     500 names

Using cross products

7 * 500 = 50x

Divide by 50

7 * 500/50 = 50x/50

70 =x

Suppose sarah is trying to design a metal box (a rectangular prism), which will hold 450 cubic centimeters of liquid. the length
schepotkina [342]
<span>So, the volume of a container can also be thought of as the amount of liquid that the container is capable of holding. It follows that 450=(length)(width)(height). The constraints of the problem say that the length of the box must be twice as large as the width, so it follows that j(height)=(2w)(w)(height)-450. This then implies that j(height)=(2w^2)(height)-450. In simpler terms, the height is defined as 450/(2w^2), or j(w)=450/(2w^2).</span>
