Answer:

7. Approximately 402.7 inches or 2pi times 64

8. 31.83 To solve this you know 2pi r is an equation for the radius. 2πr=200 and r=200/2π=100/π= 31.83.

9. The one with pi in the equation because 3.14 is only a piece of pi but the symbol represents the whole number which goes on forever.

The diameter of a circle measures 7 5/6 inches. What is the radius of the circle? Enter your answer as a mixed number in the box

andrew-mc [135]

The radius of the circle expressed as a mixed number is: $3\frac{11}{12}$ inches.

<h3>What is the Radius of a Circle?</h3>

Radius of a circle = half the measure of the diameter of a circle.

Given:

diameter of a circle = $7\frac{5}{6}$ inches

Therefore:

Radius of the circle = 1/2( $7\frac{5}{6}$ )

= 1/2(47/6)

= (1 × 47)/(2 × 6)

= 47/12

= $3\frac{11}{12}$ inches.

Therefore, the radius of the circle expressed as a mixed number is: $3\frac{11}{12}$ inches.
