the circumference of the base of a right circular cylinder is 176cm. if the height of the cylinder is 1m, find the lateral surface area of the cylinder.
Answers
Answer:
1.76 m²
Step-by-step explanation:
the circumference of the base of a right circular cylinder is 176cm. if the height of the cylinder is 1m, find the lateral surface area of the cylinder.
circumference of the base = 2 π R
R = Radius of base π = 22/7
=> 176 = 2 π R
=> 176 = 2 (22/7) R
=> R = 28
Radius = 28 cm
Height = 1 m = 100 cm
Lateral surface area = 2 π R * Height
2 π R = 176 cm = 176/100 m Height = 1 m
= (176/100) * 1
= 1.76 m²
Answer:1
Step-by-step explanation:
Height(h) of the cylinder =14 cm
Curved surface area of cylinder=
88cm square
2πrh = 88cm
2 * 22/7 * r * 14= 88cm
2 * 22 * r * 14 = 88 * 7
612r = 612 cm
r = 612 cm/ 612
r = 1 cm
Therefore, the radius of the base of the cylinder is 1 CM.
Diameter = radius+radius
= 1 CM + 1 cm
= 2 cm
