Kipish [7]

Answer:    70

plz give brainliest

Step-by-step explanation:

Solution:

Since

96 : 160 = 42 : X

Then we know

160/96 = X/42

Multiplying both sides by 42 cancels on the right

42 × (160/96) = (X/42) × 42

42 × (160/96) = X

Then solving for X

X = 42 × (160/96)

X = 70

Therefore

96 : 160 = 42 : 70

A cylinder has a surface area of 5652 square millimeters. If the diameter of the cylinder is 30 millimeters, what is the height?
o-na [289]
The formula for the surface area of a cylinder is:

\sf A=2\pi rh+2\pi r^2

Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):

\sf 5652\approx 2(3.14)(15)h+2(3.14)(15)^2

Simplify:

\sf 5652\approx 94.2h+1413

Subtract 1413 to both sides:

\sf 4239\approx 94.2h

Divide 94.2 to both sides:

\boxed{\sf h\approx 45~mm}

So the height is approximately 45 millimeters.

Find the S.A of all the cubes and then add them together.

S.A = 6a²

a is the side length

S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6

Now add them all together.

54 + 24 + 6 = 84

So the total surface area is 84

Hope this helps :)
