a cone has a volume of 1,570in3. If the height of the cone is 15 inches. Calculate the radius of the cone?
spin [16.1K]

Answer:

approximately 10

Step-by-step explanation:

Volume = 1/3h times \pi times radius square

1570 = 1/3 x 15 x 22/7 x r^{2}

1570 = 5 times \frac{22}{7} times r^{2}

1570 = 15.71r^{2}

\frac{1570}{15.71} = \frac{15.71 r^{2}}{15.71}

99.9 = r^2

\sqrt{99.9} = r

≅10
