Question

Area of the base of a cone is 1386 sq.cm.and it's height is 28cm. .Find it's surface area​

Answer 1

Answer:

Right circular cone

Solve for volume

V=12936cm³... ....

Answer 2

Answer:

Let the base of the cone is r respectively

because the base is a radii of a cone.

Then,

$r + l = 28$total surface area of a cone = πr(l+r)

so,

• 22/7*(28+1386)
• 22/7*(1414)
• 22(202)
• (4444) answer
