Question

total surface area of right circular come whose radius is 7 cm and slant height is 3cm is ​

Answer 1

The formula for the Total Surface Area of a Right Circular Cone is πrl + π (r^2) .

T.S.A = [ (22/7) * 7 * 3 ]  +  [ (22/7) * (7^2) ]

T.S.A = 66 + ( 22 * 7 )

T.S.A = 66 + 154

T.S.A = 220 cm^2

Answer 2

Answer:

plz mark as brainlist

Step-by-step explanation:

total surface area of cone=πr(l+r)

r=7,l=3

22/7×7(3+7)

22(10)

22×10=total surface area of cylinder

220cm is total surface area of cone
