Volume of a cylinder= (height) x area of the base (circle)

We know the height = 160 cm (given), let's find the radius of the base.

The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm

Area of circle = πR²=π(13.993)² = 615.128 cm²

Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³

What is the Area and Perimeter for tbe rectangle?

Amanda [17]

<h2>Given :-</h2>

length of rectangle = ( 4n-5 )

breadth of rectangle = ( 3n-2)

Area and perimeter of rectangle.

<h2>solution :-</h2>

by the question ,

We know the area of rectangle = length × breadth

Area = (4n -5) (3n-2)

$= {12n}^{2} - 8n - 15n + 10$

$= {12n}^{2} - 23n + 10$

now ,

perimeter = 2 ( length + breadth (

= 2 ( 4n-5 + 3n-2)

= 2 ( 7n-7)

= 14n -14

I hopes this helps.
