Answer:

81πinc^3

Step-by-step explanation:

Volume of glass = π(3)^2(12) = 108πin^3

Volume of water in glass = π(3)^2(3) = 27πin^3

Volume needed to fill completely = 108π - 27π = 81π^3

The length of an arc of a circle is 7.34 units, and the measure of the corresponding central angle is 81 degrees. What is the ap
GuDViN [60]

Answer:

A.  5.19 units

Step-by-step explanation:

\textsf{Arc length}=2 \pi r\left(\dfrac{\theta}{360^{\circ}}\right) \quad \textsf{(where r is the radius and}\:\theta\:{\textsf{is the angle)}

Given:

  • \theta = 81°
  • Arc length = 7.34 units

Substituting given values into the equation and solving for r:

\implies 7.34=2 \pi r\left(\dfrac{81^{\circ}}{360^{\circ}}\right)

\implies 7.34=r\left(\dfrac{18 \pi}{40}\right)

\implies 7.34 \cdot 40=18 \pi r

\implies 293.6=18 \pi r

\implies r=\dfrac{293.6}{18 \pi}

\implies r=5.19 \sf \: units \:(2\:dp)
