LO: Calculate the volume and surface area of a Sphere and Cone (Grade A)
Example 1 Cone
Curved surface area of a cone = TT r l
Total surface area of a cone = TT r l + TT r²
Volume = TT r²h 3
Curved surface area = TT x 5 x 12 = =
Base area = TT r²
= TT x 5²
= 78.54
Total surface area = = cm²
Volume = TT x 5² x 10 = = cm³
R = 5
H = 10
L = 12
