Answer:

23 inches

Step-by-step explanation:

Circumference = 2πr

72 = 2×3.142×r

Divide through by 2 × 3.142

r = \frac{72}{2 * 3.142}

r = 11.458 inches

Diameter = 2r

Diameter = 2* 11.458 = 22.92

= 23 inches to the nearest inch

Answer:

The answer to your question is   b = 8.06 cm

Step-by-step explanation:

Data

hypotenuse = c = 9 cm

long leg = b = ?

short leg = a = 4 cm

Process

This is a right triangle so we must use the Pythagorean theorem to find the length of the long leg (b)

                      c² = a² + b²

-Solve for b²

                      b² = c² - a²

-Substitution

                      b² = 9² - 4²

-Simplification

                       b² = 81 - 16

                       b² = 65

-Result

                      b = 8.06 cm
