Problem 1 :
A paper cup shaped like a cone and has a diameter of 6 cm and slant height of 7.5 cm. How much paper is need to make the cup ?
Problem 2 :
The roof is shaped like a cone with the diameter of 12 feet. One bundle of shingles cover 32 square feet. How many bundles should you buy to cover the roof.
Problem 3 :
Two Florida Atlantic University stickers are placed on opposite sides of megaphone. Estimate the percent of the surface area of the megaphone covered by the stickers. Round the answer to the nearest percent.
Problem 4 :
Total surface area of a cone whose radius as p/2 and slant height as 2l is:
(a) 2πp(l + p) (b) πp(l + (p/4))
(c) πp(l + p) (d) 2πpl
Problem 5 :
If the slant height of a cone 12 cm and radius of the base is 14 cm, then the total surface area is.
Problem 6 :
The radius and height of a cone are in the ratio 4:3. The area of the base is 154 cm^{2}. Find the curved surface area.
Problem 7 :
There are two cones, the curved surface area of one cone is twice that of the other. The slant height of later is twice that of the former. Find the ratio of their radii.
1) 70.65 cm^{2} 2) 8 bundles 3) 12% |
