(B) The total surface area of a cone is given by the formula: $TSA = \pi r(r + l)$,where $r$ is the radius and $l$ is the slant height.Given: $r = 10\, cm$,$TSA = 880\, cm^2$,and $\pi = 22/7$.Substituting the values into the formula:$880 = (22/7) 	imes 10 	imes (10 + l)$$880 	imes 7 = 220 	imes (10 + l)$$6160 = 220 	imes (10 + l)$$10 + l = 6160 / 220$$10 + l = 28$$l = 28 - 10$$l = 18\, cm$.Thus,the slant height of the cone is $18\, cm$.

The radius of a cone is $10\, cm$ and the total surface area of a cone is $880\, cm^2$. Find the slant height in $cm$. (Use $\pi = 22/7$)
