The surface area of a cone is given by the formula s=3.14l+3.14r2 solve for the formula for l

Hello from MrBillDoesMath!

l = s/3.14 - r^2

Discussion:  

s = 3.14 l + 3.14 r^2        =>  divide both sides by 3.14

s/3.14 = l + r^2               => subtract r^2 from both sides

(s/3.14) - r^2 = l

Thank you,

MrB

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
