HLW MATE!
WE Know that CURVED SURFACE AREA OF CYLINDER IS =2pieRH
SO FIRSTLY We need to find RADIUS(R) from GIVEN CIRCUMFERENCE
circumference=2pieR
:22=2pieR
R=22×7/22×2=3.5cm
now putting the given values in CURVED SURFACE AREA's formula
:2×22/7×3.5×300=66,000 square cm
or 0.66 square meter
THANK U☺

Answer:
6600cm^2
Step-by-step explanation:
we know csa of cylinder=2pie*r*h
we need to find r circumference =2pie*r
so we get 3.5
then 2x22/7x3.5x300 =
6600 cm^2
hope it helps
