The surface area of a cone consists of the area of lateral side and the area of the base. The area of lateral side is determined using (π × r × s), s represents the slant height. The area of the base is determined using the formula of the area of a circle.
area of lateral side + area of base = surface area
(π × r × s) + (π × r²) = surface area
Input the numbers
(π × r × s) + (π × r²) = surface area
(π × 10 × s) + (π × 10²) = 150π
10πs + 100π = 150π
10πs = 150π - 100π
10πs = 50π
s = 50π/10π
s = 5
The slant height is 5 inches

Step-by-step explanation:
when you let x=7.1
-7.1+(-5.8) Adding a negative is the same as subtracting.
-7.1-5.8=<u> -12.9</u>
Because the sectors are of equal size, each sector has the same probability of happening.
So for every number, you have a probability of 0.2 of it appearing.
Because you have three odd numbers, the probability to land on an odd number on each spin is 0.6. You can also say that the probability to not have an odd number is 0.4.
So what is the probability to have 0 odd number in two spins?
What is the probability to have 1 odd number in two spins? You can have one odd number on the first or one odd on the second spin, that is why we add the probabilities.
What is the probability to have 2 odd numbers in two spins?
To verify if we did a good job, we add all the probabilities. We should get 1.
.
So to slide your bars, you slide them up to the number I gave you for each case.
Answer:
Step-by-step explanation:
Since surface area consists of the sum of the outer faces of each polygon, the ratio of the two surface areas will be equal to the ratio of the side lengths squared (since we multiply them to get area).
The ratio of the corresponding side lengths of the solids are . Therefore, the ratio of their surface areas must be
