Question

Bailey bought a large pizza with a 16 inch diameter. She wants to know the circumference of the pizza. Use 3.14 for pi and round to the nearest tenth, if necessary.

Answer 1

The formula for the circumference is 2 pi r

the diameter is 16, but you need the radius, so you would divide 16 by 2 and get 8.

then you would do 2*3.14*8=50.24

the final answer would be 50.2 once you rounded to the nearest tenth

Answer 2

2(3.14)(8) = 50.24
circumference = 50.24
