Answer:

A.

Step-by-step explanation:

The formula for circumference is:

C=2\pi r

We know that the circumference is 8π inches. So, substitute 8π for C:

8\pi =2\pi r

Solve for r. Divide both sides by 2π. So:

r=\frac{8\pi}{2\pi}=4

Therefore, the radius is 4 inches.

Hence, our answer is A.

Answer:

A

Step-by-step explanation:

Remarks

  • The given angle is an exterior angle.
  • It's value is 46 degrees.    
  • An exterior angle is the sum of the two remote angles. (A remote angle is one that is not supplementary  to the given exterior angle.

Solution

  • 46 = <u + <t
  • <t = 29
  • 46 = <u + 29               Subtract 29 from both sides.
  • 46 - 29 = <u
  • <u = 17 degrees
