Question

the circumference of the base of right circular cylinder is 176 cm and it is 1m hight find the lateral surface area of the cylinder​

Answer 1

Answer:

Step-by-step explanation:

first 1 m to cm=100 cm

h=100 cm

circumference =2πr

176=2πr

∴r=176/2π--------------(1)

now C.S.A of cylinder = 2πrh

C.S.A= 2*π*176/2*π*100

C.S.A= 17600 cm²

Answer 2

LSA CYLINDER =

$2\pi \: r \: h$

Circumference =

$2\pi \: r$

= >176 = 22/7 × 2 × r

(176 × 7) ÷ (22 × 2) = R

28cm = R

LSA = 2 × 22/7 × 28 × 100

= 17600 cm^2
