Question

This figure is

1/4


of a circle.
What is the best approximation for the perimeter of the figure?
Use 3.14 to approximate pi.


A.4.7 cm

B.7.7 cm

C.10.7 cm

D.18.8 cm

Answer 1

10.7

Explanation:

10.7

Answer 2

The perimeter of the 1/4 of the circle is = (pi/2 + 2)r

Here pi = 3.14, r = 3

Now plug in the values in to the above formula.

=(3.14/2 + 2) 3

= (1.57 + 2) 3

= 3.57*3

Perimeter of the circle = 10.71 cm.

The answer is C) 10.7 cm
