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
