Question

What is the approximate perimeter of the figure?




A.
3.1 inches


B.
6.3 inches


C.
7.1 inches


D.
12.3 inches

Answer 1

posting the figure give me a sec

Answer 2

B?

Answer 3

The perimeter of a circle is 2π.radius, as it is 1/4 of a circle this perimeter will be
P=π.radius/2+2.radius

Answer 4

3.14 x 4 = 12.56? @gaos √ or x

Answer 5

you divide it

Answer 6

by 4?

Answer 7

3.14x4/2=6.28

Answer 8

Oh oops! My mistake... Xp Thank you! ^u^

Answer 9

so its B

Answer 10

No, itunot done yet. I want now that you solve
6.26+2.radius

Answer 11

oh

Answer 12

8.26

Answer 13

And the radius is 2 not 4.

Answer 14

ya i did 6.26 + 2

Answer 15

Circumference is \(2\pi r\)

So since we havee 1/4 the circle, we have \(\dfrac{C}{4} = \dfrac{\pi r}{2}\)

Answer 16

Then you add radius twice.

Answer 17

12.56 -3- ?

Answer 18

wait no 8.28

Answer 19

So in fact
P=3.14.2/2+2.2
P=3.14+4
P=7.14

Answer 20

So perimeter is pretty much \(\dfrac{\pi r}{2}+r+r\)
