Step-by-step explanation:
4*6=24
5*8=40
Answer:
-80
Step-by-step explanation:
The average rate of change is
a.r.c = f(4) - f(1)
--------------
4-1
f(4) = 244 and f(1) = 484
a.r.c = 244 - 484
--------------
3
= -240/3
=-80
Answer:
Step-by-step explanation:
We need to first find the radius of the sphere.
The surface area of a sphere is given as:
where r is the radius
Therefore:
The radius of the sphere is 4 cm.
The volume of a sphere is given as:
Therefore, the volume of the sphere of radius 4 cm is;
The volume of the sphere is
Answer:
Step-by-step explanation:
