Answer:
no, it is not the answer is(2,-2)
If you picture a cylinder rolled out flat. there would be two circles for top and bottom and then a rectangle for the side. The rectangle would have width equal to height and length equal to circumference.
So then the areas of the pieces are added together to get total surface area.
= 2pi(3x-2)^2 + 2pi(3x-2)(x+3)
and you can simplify this is you want by multiplying through and combining like terms.
= 2pi(12x^2 - 5x -2)
or factor more to simplify the solution.
= 2pi(3x-2)(3x-2+x+3)
= 2pi(3x-2)(4x+1)
Answer:
the correct answer is c
Step-by-step explanation:
Answer:
Option A is the correct answer.
Explanation:
Let A be the base area and h be the height of prism.
Volume of prism = Base area x Height = a x h =ah
Now we have base area of pyramid = Base area of prism = a ( both have same type of base)
Height of pyramid = 3 x height of prism = 3h
Volume of pyramid = 1/3 x Base area x Height = 1/3 x a x 3h = ah
Comparing both volumes, we will get Volume of prism = Volume of pyramid
So their ratio is 1.
Option A is the correct answer.
