And please show your work

Step-by-step explanation:

1. The radius of a circle is half the diameter 16/2=8ft

2. The diameter of a circle is double the radius so 3*2=6m

3. this i your circumference formula

add both together

im not sure

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
