A regular 40-sided polygon is rotated with its center of rotation at its center. What is the smallest degree of rotation needed
mina [271]
Hey! the answer would be A regular 40-sided polygon has an interior angle equal to:
(40 - 2) (180) /40 = 171 degrees

The interior angle is also the smallest angle that is needed to  rotate the polygon and map it unto itself. So, the smallest degree of rotation needed to map the polygon back to itself is 171 degrees.

What is the volume of the oblique cylinder rounded to the nearest cm^3?
SVETLANKA909090 [29]

Answer: 32009355.90cm^3

Step-by-step explanation:

Formula: V=Bh\\

Since the base is a circumference, we can replace B for the area of a circumference formula.

V=\pi r^2h

What we have here is 12 ft as the diameter of the circumference. A diameter is twice the radius, therefore we can conclude that if we take the diameter and divide it by 2, it will give us the radius.

12/2=6ft this is the radius.

Now plug all this information into your formula.

V=(3.14)(6ft)^2(10ft)\\V=(3.14)(36ft^2)(10ft)\\V=1130.40ft^3

Our values are in feet but the question requires cm. Let's convert from ft^3 to cm^3.

Normally, our conversion factors are raised to the power of 1, but in this case it's raised to the power of 3. So, first let's see how many cm are 1 ft.

1ft=30.48cm

Here is where magic comes. We can raise both to the power of 3, in order to find the cubic ft and cm that we need as our conversion factors.

(1ft)^3=(30.48cm)^3\\1ft^3=28316.8cm^3

Now we have our conversion factors.

1130.40ft^3(\frac{28316.84cm^3}{1ft^3})=32009355.90cm^3
