A farmer wants to paint a silo with red paint. He only wants to paint the sides. If the tank has a height of 13 maters and a diameter of 10 meters, how much paint will he need?

Step-by-step explanation:

The Silo is cylindrical in shape.

The farmer wants to paint only the sides of the Silo with red paint. This means that the top and bottom of the Silo will not be painted.

The formula for determining the surface area of a cylinder is expressed as

Surface area = 2πr² + 2πrh

Since the top and bottom is not included, the formula becomes 2πrh

From the information given,

h = 13 meters

Diameter = 10 meters

Radius = diameter/2 = 10/2 =

5 meters

Therefore, the amount of paint that would be needed in square meters is

2 × 3.14 × 5 × 13 = 408.2m²

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
