Estimate the radius of the object. Round to the nearest hundredth if necessary. (Don’t guess please).

13.98 mm

Step-by-step explanation:

C=πd

C=2πr

8.9=2πr

4.45=πr

13.98≈r

Therefore, the radius of the object is about 13.98 mm

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
