Cone: a solid with one base that is a circle, and a curved, smooth lateral surface that comes to a point, the apex.
No, because it has a curved lateral surface area.
c. LA = ½ (12 π ) (13)
LA = 78 π cm²
SA = LA + πr²
SA = 78 π + 36π
d. LA = ½ (13 π) (12)
LA = 78 π cm²
SA = LA + πr²
SA = 78 π + 6.5 ² π
Cylinder A has a height of 8cm.
Cone B has a slant height of 8cm.
Each shape has a base radius of 6 cm.
Find the lateral area and surface area of Cylinder A and Cone B.
Finish the worksheet on lateral and surface area.
