A cone and a cylinder have congruent height and bases. The volume of the cone is 18. What is the volume of the cylinder? Explain please and thank you!

Answers

The volume of a cone is given by the formula: V = 1/3 * B * h where B is the area of the base and h is the height of the cone.

The volume of a cylinder is given by the formula V = B*h where B is the area of the base and h is the height of the cylinder.

1/3 Bh = Bh because the bases and heights of the two solids are the same.

The volume of the cylinder is 3 times the volume of the cone.
3 * 18 = 54 which is the volume of the cylinder.

Correct Answer:

The cones are not congruent because one cone is oblique, which makes the length of the slant heights different. Having the same radius, height, and volume does not make the cones congruent when the corresponding slant heights are not equal. Congruent cones must have congruent corresponding slant heights, with all other corresponding parts being congruent.

Into an improper fraction. An improper fraction is a fraction where the denominator is smaller than the numerator.

Example: Mixed number: 1 2/3
Improper fraction: 5/3

Yes, it is. Actually, it depends on if the fractions you're dividing have like or unlike denominators. If they have unlike, then yes. Let's say I was dividing 3/4 by 1/2. I would first, find the LCM (least common denominator) which in this case is already 4. I would then make 1/2 into 4ths. Lets see:1/2x 2/2 (how many times 2'goes into 4) and I get 2/4. Now I'm ready to divide. Sorry, this problem you can't divide but you can subtract:3/4-2/4= 1/4Hope I helped!

You need to paint the three rectangular sides of the right triangular prism below. How much paint do you need to cover all the rectangular faces of the prism?A prism which has a right triangle for the base and a height of 12 inches. The legs of the right triangle are 5 inches and 12 inches.

A. 300 in²
B. 360 in²
C. 204 in²
D. 420 in²

Answers

Answer:

B. 360 in²

Step-by-step explanation:

Rectangle 1

length = 12 in

breadth = 12 in

Surface area = length × breadth

⇒Surface area = 12 × 12

⇒Surface area = 144 inch²

Rectangle 3 (behind)

length = 12 in

breadth = 13 in

Surface area = length × breadth

⇒Surface area = 12 × 13

⇒Surface area = 156 inch²

Rectangle 2

length = 12 in

breadth = 5 in

Surface area = length × breadth

⇒Surface area = 12 × 5

⇒Surface area = 60 inch²

Adding the 3 areas we get

144+156+60 = 360 in²

∴ 360 in² of paint is needed to cover all the rectangular faces of the prism.

To solve this problem, one must find the surface area of the rectangles. This is the total area of each rectangle added together. The formula for the area of the rectangle is w*l=A

Rectangle one: 13*12 = 156 in^2

Rectangle two: 5*12 = 60 in^2

Rectangle three: 12*12 = 144 in^2

156 + 60 + 144 = 360 in^2

This means total to paint the rectangle sides of the prism, we need 360 in^2 of paint.
