A circle with a diameter of 8 is cut into 4 equal pieces. What is the total perimeter of the 4 pieces?

Question

A) 16 8Pi

B) 32 8Pi

C) 64 8Pi

D) 32 16Pi

E) 64 16Pi

Please explain.

Answer 1

well the formula for the circumference of a circle is 2rPi.  so you need this formula, plus the total length of the lines that dissect your circle multiplied by 2 (which add to 32 [8+8]x2).  so the correct answer is 'B'.  the answer translates to this formula....

[dissecting lines x 2] 32+ 2 x radius x Pi

assuming the spaces in your question represent '+'

Answer 2

circumference plus 4 x the diameter

πd + 4d

d(π + 4)

d = 8

8π + 32

which I think is B

.

Answer 3

the answer is B
