Answer:
Step-by-step explanation:
Remember, the formulas for the lateral surface area of a pyramid is 12pl and the total surface area is 12pl+B .
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder.
So, the formula for the lateral surface area of a right cone is L.S.A=πrl , where l is the slant height of the cone.
Find the lateral surface area of a right cone if the radius is 4 cm and the slant height is 5 cm.
L.S.A=π(4)(5)=20π≈62.82 cm2
No. Since we cannot factor,
.
Hope this helps.
