Answer:

given that, diameter= 2m then r = 1m

height = 4√3 m

Step-by-step explanation:

height = ( √rsquare + hsquare)

= ( √ 1×1 + 4√3× 4√3)

= ( √ 1+ 16.3 )

= ( √ 1+ 48)

= ( √ 49)

= 7 m

therefore slant height = 7m

C.S.A of cone = (π× r×<l )

= 22/7 × 1×7

22msqr ( 7 get cancel)

Therefore , the CSA of cone = 22 m square
