Answer:

C = 100 pi cm

Step-by-step explanation:

Circumference is given by

C = 2*pi*r

We are given the radius is 50

C = 2*pi*50

C = 100 pi

We cannot approximate pi since we are asked for the exact value

C = 100 pi cm

A driveway is 60-feet long by 6-feet wide. The length and width of the driveway will each be increased by the same number of fee
Dafna11 [192]

Answer: C) 4(x+33)

Step-by-step explanation:

1. You know that the perimeter of the larger driveway is represented with the following expression given in the problem:

(x+60)+(x+6)+(x+60)+(x+6)

2. When you simplify it and add the like terms, you obtain:

x+60+x+6+x+60+x+6=4x+132

3. Now, you can factor out 4. Therefore, you can write the expression as below:

4(x+33)

4. So, you can conclude that the answer is the option C.
