The surface area of a cone is given by the formula S = πl + πr2. Solve the formula for l.

l=(S-πr²)/π

Step-by-step explanation:

To solve for l, we use our algebraic rules to get l alone.

S=πl+πr²            [subtract πr² on both sides]

S-πr²=πl             [divide both sides by π]

(S-πr²)/π=l

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.
