10=2*pi*r Solve for r: 10/(2*pi)=r 1.591=r so radius rounded to nearest tenth is 1.6

Circumference circle = pi* r^2 Load and crunch previous formula was for area. The correct answer is 2*Pi*r = 24*Pi = 75.4 cm (rounded to nearest tenth). I stand corrected. One needs be more careful. Thank you.

Distance around circle = 2*pi*r = 157.1 so r = 157.1/(2*pi) = 25.00 ft so, to the nearest tenth of a foot, 25.0 ft
r = sqrt(400/pi) = 11.3 cm
Rounded to the nearest whole number it is 197

To find the volume of a cone, you use the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone. Calculate the volume of each cone by plugging in the given values for r and h into the formula. Round your final answers to the nearest tenth.
