A cylinder has a bar radius of 14cm and 18cm. How many litres can it hold?correct to the nearest metre. Take pie to 22/7

Am i to solve it?

I assume you meant:

a radius of 14 cm and a height of 18 cm
then the volume is π(14^2)(18) cm^3 = 3528π cm^3

"How many litres can it hold?" , how many litres of what?
generally 1000 cm^3 of water is 1 L
so 3528π cm^3/1000 cm^3 = appr. 11.08

"correct to the nearest metre" , makes no sense, a litre is a measure of volume, a metre is a linear measure.

btw, nobody uses 22/7 for π anymore, hand-held calculators that contain π correct to about 10 decimal places were invented over 30 years ago.

To calculate the volume of the cylinder and determine how many liters it can hold, we need to use the formula for the volume of a cylinder: V = πr^2h.

Given:
Radius (r) of the cylinder's base = 14 cm
Height (h) of the cylinder = 18 cm
Approximate value of π = 22/7

Let's calculate the volume:

Step 1: Calculate the area of the base (A) using the formula A = πr^2.
A = (22/7) * (14 cm)^2
A = (22/7) * 196 cm^2
A ≈ 615.43 cm^2 (rounded to 2 decimal places)

Step 2: Calculate the volume (V) of the cylinder using the formula V = Ah.
V = 615.43 cm^2 * 18 cm
V ≈ 11,077.74 cm^3 (rounded to 2 decimal places)

Step 3: Convert the volume from cm^3 to liters. Since 1 liter is equal to 1000 cm^3,
Volume in liters = 11,077.74 cm^3 / 1000
Volume ≈ 11.08 liters (rounded to 2 decimal places)

Therefore, the cylinder can hold approximately 11.08 liters of liquid.
