A.4 cm
B.8 cm
C.12 cm
D.16 cm

Answer 1

Hint: \(\sf Circumference = 2 \times \pi \times radius\)

Answer 2

C=2πr
C=25.12

Answer 3

so 2x3.14 but how do i get the radius

Answer 4

So you see they gave you the circumference.
And that is equal to 25.12

So plug it all in to the formula:

\(\sf 25.12 = 2 \times 3.14 \times radius\)

Answer 5

And then you just divide to isolate radius by itself and you have your answer :)

Answer 6

so what is the radius??????

Answer 7

You tell me.

Answer 8

its simple 25.12/2=3.14 x radius

Answer 9

Do the division
\(\sf \Large\frac{25.12}{2 \times 3.14}\)

Answer 10
