Answer:
CSA = 165 cm^2
TSA = 251.625 cm^2
Step-by-step explanation:
Given,
Diameter of the base of the cone = 10.5cm
Therefore, radius of the cone = 10.5/2 cm
= 5.25 cm
slant height(l) = 10 cm. (a) CSA of cone = πrl = 22/7×5.25×10 cm^2
= 165 cm ^2
(b) TSA of cone = πr(l+r)
= 22/7×5.25(10+5.25) cm^2
= 22/7×5.25×(15.25) cm^2
= 251.625 cm ^2
