Answer B is correct. Sum is the answer to an addition problem, so sum of 8 and 2 would be 8+2.
Answer:
cubic inches
Step-by-step explanation:
Diameter is increasing at 3 inches more than time, When t = 3
Diameter (d) = 3+3 = 6
d = 6
Radius is HALF of diameter, so
r = 6/2 = 3
Now, the volume of a sphere is given by the formula:

Putting r = 3, we get:

The volume would be 36π
Answer:
600
Step-by-step explanation: 360÷6=60 60×10=600
Answer:
The APY of the saving account is 4.0474%
Step-by-step explanation:
We know the formula for APY which is given by

here, r= interset rate = 3.9742% = 0.039742
n = compounding cycles = 12
On plugging these values in the above formula, we get

On simplifying this we get
APY =0.04047395=4.0474%
