Curved surface area and circumference of the base of a solid right circular cylinder are 4400 sq. cm and 110 cm respectively. Find its height and diameter.
It is given that C.S.A. of the cylinder =4400 sq. cm.We know that C.S.A of a right circular Cylinder =2π×r×h ⇒2πrh=4400 ⇒(110)h=4400 ⇒h=4400110 =40 cm Height =40 cmCircumference of the base of the cylinder is 110 cm⇒2πr=110
⇒2×227×r=110
⇒r=352
⇒r=17.5 cm
Diameter 2r=2(352)=35 cm
