Surface area of cone is 60π cm^2
Option A is correct.
Step-by-step explanation:
We are given:
Height = 17cm
Radius= 3cm
We need to find surface area of cone in terms of π.
The formula used to find surface area of cone is:

Answer:
The greatest number of arrangements that he can make if every balloon is used is 8.
Step-by-step explanation:
The greatest number of arrangements will be the greatest common factor between 24 and 32.
GCF of 24 and 32:
We keep factoring both numbers by prime factors, while they can both be divided by the same number. So
24 - 32|2
12 - 16|2
6 - 8|2
3 - 4
There is no factor for which we can divide both 3 and 4. So the GCF is 2*2*2 = 8.
This means that the greatest number of arrangements that he can make if every balloon is used is 8.
