Answer 1

IM DOING THIS RIGHT NOW OMG THATS CRAZY I KNOW THE ANSWERRR

Answer 2

B

Explanation:

`\boxed{circumference \: of \: circle = 2\pi r}`

Since the diagram shows that the diameter of the circle is 6cm, we can find the radius by dividing it by 2.

(Diameter= 2 ×radius)

Radius

= 6 ÷2

= 3 cm

Circumference of circle

= 2(π)(3)

= 6π

= 18.8 cm (3 s.f.)

Thus, the answer is B.
