15m + 2n, first you have to pair the matching variables, 8m and 7m along with the sign in front of them. so 8m(+7m), you would then add those then do the same with the other, +4n(postive) and -2n, so subtract 2 from 4 and get 2. put them together and it’s 15m+2

the volume of a right circular cone that has a height of 17 m and a base with a circumference of 6.3 m. Round your answer to the
spin [16.1K]

Answer:

When circumference = 6.3 then radius =

circumference / (2 * PI) = 6.3 / (6.283) =

radius = 1.0027

Cone Volume = PI * radius ^2  * height / 3

Cone Volume = PI * 1.0027^2 * 17 / 3

= 17.898 cubic meters which rounds to

17.9 cubic meters
