You wanna times that with the radius (r).
The radius is half of the diamater so divde the diameter by 2 then mutiply whatever u get with 3.14
Then the final step is do 3.14 x radias then times 2.

You need to know that within one parallelogram, the same-side interior angles are supplementary angles, meaning that they add up to 180°.
---------------------------------------------------------------------------------------
Given
(2x+15)+x=180
Expand parenthesis
2x+15+x=180
Combine like terms
3x+15=180
Subtract 15 on both sides
3x+15-15=180-15
3x=165
Divide 3 on both sides
3x/3=165/3
x=55

Circle C) shape created when a rectangle is rotated about the y-axis
Cylinder D) parallel cross section of a sphere
Cone E) perpendicular cross section of a pyramid
Answers
Answer:
Step-by-step explanation:
Perpendicular cross section of a pyramid ------- triangle.
Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.
Perpendicular cross section of a cylinder ------- rectangle
diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)
parallel cross section of a sphere ------ circle
when you cut sphere a side would appear with shape of circle.
shape create.... ----- cylinder.
one side of rectangle would be high of cylinder and other would be radius of it.
last one is cone. If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.
