What is the radius of a circle with circumference 17 mm? Round to the nearest tenth. Use 3.14 for TT.

Answer 1

Answer: 2.7mm

Explanation:

The formula for the circumference of a circle is given as 2πr. In thkw case, thw circumference is 17mm.

Therefore, 2πr = 17

2 × 3.14 × r = 17

6.28r = 17

r = 17/6.28

r = 2.7mm

Therefore the radius of the circle is 2.7mm
