AZ:

so the diameter is 2.5 what is the radius? the radius is half of the diameter

AZ:

after that, we can find the circumference (although this is a weirdly worded question, you would assume they meant surface area of the lollipop but they just want the circumference of the circle) the formula for circumference is 2*pi*r where pi is $$\pi$$ which is approximately 3.14 and r is the radius of the circle

Tonycoolkid21:

what do i do sorry

AZ:

divide 2.5 by 2 that way you'll have the radius

Tonycoolkid21:

1.25

AZ:

now you just find the circumference Circumference = 2 * pi * radius and the radius is 1.25

Tonycoolkid21:

2 x 1.25

Tonycoolkid21:

@AZ

AZ:

You forgot about pi or $$\pi$$ pi is 3.14 so 2 * 3.14 * 1.25

Tonycoolkid21:

7.85
