Best Answer
Le t the radius=R
and height =H
Curved surface area of the cylinder, S=2πRH= 4400 cm sq
Circumference of the base, C=2πR =110 cm
2πRH= 4400 and 2πR= 110
Hence H=2πRH/2πR =4400/110=40 cm
Since circumference, C=2πR =110
and R= C/2π =110/2π=55/π cm
Volume, V=πR²H =π(55/π)²×4=38515.496 cm²

csa of cylinder is 2Πrh
base is circular so
circumference is 2Πr
=2×22/7 ×110
csa = 2×22/7×110 × x
4400 = 2×22/7 × x
x =700cm
height is 700cm
base is circular so
circumference is 2Πr
=2×22/7 ×110
csa = 2×22/7×110 × x
4400 = 2×22/7 × x
x =700cm
height is 700cm
make me brainliest
and put this answer in equation replacing x by 700 and u their is ur answer
thx bro
brainliest pls
did i help you???
ok
thanks brother
no problem brother
