Answer:
The answer is 4
Step-by-step explanation:
We know that
[surface area of a sphere]=4*pi*r²
r²=surface area/(4*pi)
r=√[surface area/(4*pi)]
surface area=450 in²
r=√[450/(4*pi)]------> r=5.98 in------------> r=6 in
the answer is
r=6 in
The answer is 7 because it’s 7

Yes, it is an arithmetic Sequence. Can you explain the question just a tad more
Step-by-step explanation:
Answer:
There are 1,037,158,320 ways to choose a committee of 18 among 33 students.
There are 4,939,200 ways to choose 5 freshmen from 7, 6 sophomores from 8, 4 juniors from 8, and 3 seniors from 10.
Step-by-step explanation:
33!/18!15! = 1,037,158,320
7!/5!2! * 8!/6!2! * 8!/4!4! * 10!/7!3!
= 7*3 * 7*4 * 7*5*2 * 10*4*3 = 4,939,200
