Question 1:
The curved surface of a right circular cone of height 15 cm and base diameter 16 cm is: A. 116πcm^2
B. 136πcm^2
Feedback Curved surface area of cone=πrl
l= √r^2+h^2
l= √8^2+15^2 =17cm.
Curved surface area =πrl
π∗8∗17=136πcm^2
l= √r^2+h^2
l= √8^2+15^2 =17cm.
Curved surface area =πrl
π∗8∗17=136πcm^2
C. 126πcm^2
D. 146πcm^2
