If the cylinder above is similar to a second cylinder that has a radius of 10mm, what is the height of the second cylinder
julsineya [31]

Answer:

The height of the second cylinder is 30mm

Step-by-step explanation:

Given

Cylinder 1:

R = 15mm

H = 45mm

Cylinder 2

r = 10mm

See attachment

Required

Determine h, the height of the small one

To do this, we make use of the following equivalent ratios;

R : H = r : h

This gives:

15 : 45 = 10 : h

Express as fraction

\frac{15 }{ 45 }= \frac{10 }{ h}

Simplify

\frac{1 }{ 3}= \frac{10 }{ h}

Cross multiply

h *1 = 3 * 10

h = 30

Answer:

55.5 u^2

Step-by-step explanation:

Split the quadrilateral into 2 triangles. There are two ways to do this, but I'm only doing one of them.

On the 5-11 triangle, use the two of the lengths and plug them into the triangle area formula. (L x W)/2 = A

5-11 triangle area: 27.5

Do the same for the 7-8 triangle. Plug it into the same formula.

7-8 triangle area: 28

Add the two areas. 27.5 + 28 = 55.5
