Answer:
9/25
Step-by-step explanation:
Two pyramids are similar. Their base edges are a ratio of 3:5. Find the ratio of their surface area.
The ratio of the surface area is calculated as the square of the ratio of the edges
Hence,
Ration of surface area = 3²/5²
= 9/25

Answer:
The probability that a randomly selected point within the circle falls in the red shaded area is p=0.75.
Step-by-step explanation:
We have to calculate the probability that a randomly selected point within the circle falls in the red shaded area.
This probability can be calculated as the quotient between the red shaded area, that is a regular pentagon inscribed in the circle, and the area of the circle.
We start by calculating the area of the circle:

Then, we can calculate the area of the pentagon as:

Then, we can calculate the probability p as the quotient between the areas:
