Question

Find the volumes of the cones whose dimensions are:
(a) base radius is = 3.5 cm, height = 12 m
(b) base radius is = 5 dm, height = 10.5 cm
(c) base radius is = 21 cm, height = 15 cm​

Answer 1

Step-by-step explanation:

radius = 14 , slant height = 50 Curved surface area of cone = pi(14)(50) = 2200 cm^2 Total surface area of cone pi r(r + l) = pi (14)(14 + 50) = 2816 ...

Answer 2

Step-by-step explanation:

1. 1. soln: base radius= 3.5 cm wrong will be right is 3.5 m not be cm Ok and height= 12 m .
