Question

find the height of cylinder if—
1.area of base 360m² and volume is 2880m³
2.perimeter of base is 160m and the curved surface area is 1440m²
​

Answer 1

Answer:

1).8m

Step-by-step explanation:

first one ans is 8metre by using volume of c

cylinder

second ans is 9 metre by using curved surface area

Answer 2

Answer:

h = 8 m & h' = 9 m

Step-by-step explanation:

Given :

1. Area of base = 360 m²

Volume of cylinder = 2880 m³

We know :

Area of base = π r²

Volume of cylinder = π r² h

= > 360 × h = 2800

=  > h = 288 / 36 m

= > h = 8 m

2. Given :

Perimeter of base = 160 m

C.S.A. of cylinder = 1440 m²

We know :

Perimeter of base = 2 π r

C.S.A. of cylinder = 2 π r h'

160 × h' = 1440

16 h' = 144

h' = 9 m

Therefore we get both required answer
