Answer:
825.663706143591cm
Step-by-step explanation:
80cm × 4 = 320cm
100cm × 3 = 300cm
The radius is 40
40 × 2 = 80cm
Circumference is πd
π80 = 251.327412287183
÷ 2 = 125.663706143591cm
In total
320 + 300 + 80 + 125.663... =
825.663706143591cm
c = 2 × 14.6 × π = 29.2 × 3.141592 = 91.7344864 ≈ 91.7
Correct anawer: B
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
or 
When a base with an exponent is divided by a base with an exponent, you subtract the exponents together. (But you can only combine the exponents when the bases are the same)
For example:
(can't combine because they have different bases of y and x)
When you multiply an exponent directly to a base with an exponent, you multiply the exponents together.
For example:
First multiply the exponents together in the denominator
Now subtract the exponents together
(two negative signs cancel each other out and become positive)
