Answer:
Step-by-step explanation:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
Given the following data;
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
Where;
V is the volume of the cone.
r is the radius of the base of the cone.
h is the height of the cone.
Substituting into the equation, we have;
Volume = 301.6 cm³ (to 1d.p)
b. The curved surface area of the cone
Where;
CSA is the curved surface area of the cone.
r is the radius of the base of the cone.
l is the curved length of the cone.
Substituting into the equation, we have;
CSA = 188.5 cm² (to 1d.p)
