Question

find the
the C.S.A and T.S.A of cone given
base radius =7cm
height=10cm
slant height=15cm
​

Answer 1

Answer:

first you need to remember the formulas without them you cannot solve any question.

Step-by-step explanation:

C.S.A OF CONE = πrl

T.S.A OF A CONE = πr (l+r)

where r is radius

l is slant height

c.s.a of cone = 22÷7 x 7 x 15

= 330 cm^2

t.s.a of cone= 22÷7 x 7 (15 + 7)

= 484 cm^2

you don't need height in this because, you have already found the slant height of a cone.

thanks :)
