Find the volume of a right circular cone that has a height of 3.9 in and a base with a radius of 14.3 in. Round your answer to the nearest tenth of a cubic inch.

Step-by-step explanation:

radiusr = 3.9 in

heighth = 14.3 in

slant heights = 14.822280526289 in

volumeV = 227.76860897791 in3

lateral surface areaL = 181.60571368226 in2

base surface areaB = 47.783624261101 in2

total surface areaA = 229.38933794336 in2

In Terms of Pi π

volumeV = 72.501 π in3

lateral surface areaL = 57.806894052526 π in2

base surface areaB = 15.21 π in2

total surface areaA = 73.016894052526 π in2

i think the correct option is the second option.

i think the answer is a.( -3, -1 )
