The lateral area of a cone is 400 pi cm^2. The radius is 10 cm. Find the slant height to the nearest tenth.
Answered by oobleck
well, a = πrs, so s = a/(πr) = 400π/10π = 40.0

Surface areas of pyramids and cones quiz
1. Use Euler's formula...V=14..E=36.. answer= a-24
2. Pierre built the model.. answer=b-pentagon
3. Use formulas to find... answer= a- 76m^2; 244m^2
4. Use formula to find... answer= b-671m^2; 725 m^2
5. Find the surface area...cylinder... answer= a- 216 pi inches^2
6. for the following question...surface area...regular pyramid.. answer= a- 72ft^2.
7. for the following question...surface area.regular pyramid..answer=c-650m^2
8. Find the slant height... pyramid...answer=c=6.9mm ...haha 69
9. Find the slant height...cone...answer=d-19m
