If the mef = 60° and the diameter of this circle is 16 inches, what is the arc length of ef? (write your answer to the nearest hundredth.)

8.38 inches (rounded up to the nearest hundredth)

Step-by-step explanation:

mEF = 60°

Diameter = 16 inches

Arc length EF is given by:

EF = × 2πr

Radius = 16 inches ÷ 2 = 8 inches

EF = × 2π(8)

EF = 8.38 inches (rounded up to the nearest hundredth)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
