I can't see the picture, can you please explain the problem in the comment bar below this so can edit my answer to help?
A notation for representing an interval as a pair of numbers. The numbers are the endpoints of the interval. Parentheses and/or brackets are used to show whether the endpoints are excluded or included.
For example, [3, 8) is the interval of real numbers between 3 and 8, including 3 and excluding 8.
Answer:
36000pi
Step-by-step explanation:
V = 4/3*pi*r^3 so we need to know r
we know surface area, which is 4pi*r^2=3600pi. so we can solve for r
r=30
so v = 4/3*pi*30^3 = 36000pi
Answer:
14
Step-by-step explanation:
f(x)=-1/3x+13
f(-3)=-1/3(-3)+13
f(-3)=3/3+13
f(-3)=1+13
f(-3)=14
