Question

the area curved surface right circular cylinder 4400 cm base 1

Answer 1

☆Hello friend☆

$circumference = 2\pi \: r$

110 cm= 2× 22/7 × radius
110 cm× 7/44= r
10×7/4= r
70/4 cm= radius.

$curved \: area = 2\pi \: rh$

4400 cm^2= 2 ×22/7 × 70cm/2 × height
4400 cm^2= 220cm× height
4400 cm^2/220 cm= height

20 cm= height

Hope it helps

Hello dear user !!!

Here is your answer,

Given :-
C.S.A = 4400 cm sq
Circumference of base = 110 cm


Circumference of base = 110
➡2πr = 110
➡2*22/7*r = 110
➡44/7*r = 110
➡r = 110*7/44
➡r = 17.5

radius = 17.5cm


C.S.A = 4400
➡2πrh = 4400
➡2*22/7*17.5*h = 4400
➡110*h = 4400
➡h = 4400/110
➡h = 40

height = 40cm


Hence, radius = 17.5cm
and height = 40cm


Hope it helps.
