Question

Two cones with same base diameter 14cm and height 24cm are joined to gether along their bases find surface of shape so formed

Answer 1

Answer:

After joining, the surface area will consist of lateral surface areas of two cones.

r = 14/2

 = 7cm

h = 24cm

l = √7² + 25² = √49+576 = √625 = 25cm

Surface area = 2×πrl = 2×3.14×7×25 = 1099 cm²
