Acone has a diameter of 7 cm and a slant height of 15.5 cm. what is the surface area of the cone?
apply this formula: sa = πr2 + πrl
1. find the radius of the measure: r =
d
2
=
7
2
= 3.5 cm
2. substitute measures into the formula: sa = π(3.52) + π(3.5)(15.5)
3. simplify the power and multiply: sa = 12.25π + 54.25π
4. add to simplify: sa =
π cm2
