Answer:
A cylinder with a volume of 27 cubic inches and a height of 3 inches
Step-by-step explanation:
- Volume of a cylinder =
r²h
(where r is the radius and h is the height)
Volume = 27
Height = 3
⇒ 27 = 3
r²
⇒ 9 = r²
⇒ r = √9 = 3
So height = radius
We are given coordinates of the triangle: A(2,2), B(7,1) and C(8,-4).
We need to rotated 90° counterclockwise about the origin.
In order to find the new coordinates of rotatation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
A(2,2) --> A'(-2,2)
B(7,1) --> B'(-1,7)
C(8,-4) --> C'(4,8)
