Tublu buys a cylindrical water tank of height 1.4m and diameter 1.1m to catch rainwater off his roof. He has a full 2 litres tin of paint in his store and decides to paint the tank (not the base). If he uses 250 ml to cover 1 2 , will he have enough paint to cover the tank with one layer of paint? [take = 3.142]

He will have enough paint to cover the tank with one layer of paint

Step-by-step explanation:

To calculate the area of the surface that has to be painted, we will have to calculate the lateral surface of the cylinder

Lateral surface of the cylinder is given by

A=2πrh

Where,

π=3.142

r=1.1/2m=

h=1.4m

A=2πrh

=2*3.142*1.1/2*1.4

=4.84m^2

He uses 250ml to cover 1m^2

To cover 4.84m^2, he will use

4.84m^2 × 250ml of paint

=1,210ml of paint is needed

He has 2 litres of paint

2litres =2000ml

Tublu has 2000ml of paint but needs 1210ml of paint

Therefore,

He has an excess of 2000-1210

=790ml

The answer is yes, he will have enough paint to cover the tank with one layer of paint.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
