Find the radius, then double the radius measurement to find the diameter.

STEP 1:
find the radius

A= πr^2
plug in known numbers

68= (3.14)r^2
divide both sides by 3.14

21.6560509554= r^2
take the square root of both sides

4.6536062312 cm= r


STEP 2:
diameter equals two times the radius

D= 2 * 4.6536062312
D= 9.3072124625 cm (9.3 cm rounded to nearest tenth)


ANSWER: The diameter is 9.3072124625 cm (9.3 cm rounded to the nearest tenth)

Hope this helps! :)
