A cone and a cylinder have the same bases and volume.How are their heights related? Explain
NikAS [45]

Answer:

Height of the cone is thrice the height of the cylinder

Step-by-step explanation:

Let 'h' b e the height of the cylinder and 'H' be the height of the cone.

Volume of cylinder = base area × h

Volume of cone = 1/3 (base area)×H

Since the volumes are equal with same base areas,

base area × h = 1/3 (base area)×H

h = H/3

Or,

3h = H

Dmitriy789 [7]

Answer:

60 degrees

Step-by-step explanation:

We are given the measures of WY and XY. Using them, we can find out 2WY=XY.

In 30-60-90 right triangle, the hypotenuse is 2 times the shortest leg. This means that this triangle is a 30-60-90 triangle. Angle Y is the angle made by the shorter leg and the hypotenuse therefore it is 60 degrees.

a line segment with points p(1 2) and q(4 3) is reflected across the line y=x. What are the new coordinates of the points of the
katen-ka-za [31]

Answer:

The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)

Step-by-step explanation:

we know that

When you reflect a point across the line y= x, the x-coordinate and y-coordinate change places.

so

The rule of the reflection of a point across the line y=x is

(x,y) -----> (y,x)

we have

Points p(1,2) and q(4,3)

Applying the rule of the reflection across the line y=x

p(1,2) ------> p'(2,1)

q(4,3) -----> q'(3,4)

therefore

The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)
