Question

A can of tuna is in the shape of a cylinder. The distance around the top of the cylinder is approximately 251.2 mm. The tuna company plans on making the cap opener the length of the radius of the top. What will the length of the cap opener be?

Answer 1

The Answer to this question is 40mm

Answer 2

Answer: 40 mm

===============================================================

Step-by-step explanation:

I'm assuming your teacher used pi = 3.14 to compute the circumference.

If so, then,

C = 2*pi*r

251.2 = 2*3.14*r

251.2 = 6.28r

6.28r = 251.2

r = (251.2)/(6.28)

r = 40 mm is the radius
