r is the decay rate, written in decimals.
t is the time
In this problem we have
so
solve for r

Answer:
Step-by-step explanation:
a^8/c
The mathematical equation for volume of a cylinder is pi times radius Squared Times height
The radius squared is 36
So 3.14 x 36 =113.04
Then you multiply 113.04 x 7 = 719.28.
Round that number and you get to 791.3.
So the answer is c
