Answer:
12 3/20 is the simplest form
Answer:
30cm
Step-by-step explanation:
Area is πr²
So,
πr²=225π
r=√225
r=15cm
Diameter=2r=30
Maths is easy peasy
Answer: 0.0123
Step-by-step explanation:
Given : Customers leaving a subway station can exit through any one of three gates.
The probability of selecting any particular gate = 
Sample size : n= 4
Using binomial distribution,
, where P(x) is the probability of getting success inn x trials , n is the number of trails and p is the probability of getting success in each trial.
Then , the probability that among a sample of 4 customers, they all exit through the same gate.

Hence, the probability that among a sample of 4 customers, they all exit through the same gate = 0.0123
Answer:
Surface area of a cone = πrs + πr2
Volume of a cone = 1/3πr2h.
The slant of a right circle cone can be figured out using the Pythagorean Theorem if you have the height and the radius.
Answers for volume problems should always be in cubic units.
