A circular table has a diameter of one.2 m Jamie wants to paint the top surface of the table if one can of paint covers in area of 2.5 m² how many cans of paint does Jamie need to buy?
To find the area of the circular table, we first need to find the radius of the table.
The diameter of the table is 1.2 m, so the radius is half of the diameter, which is 0.6 m.
The formula for the area of a circle is A = πr^2, where r is the radius.
Plugging in the values, we get:
A = π(0.6)^2
A = 3.14 * 0.36
A = 1.128 m²
Now, we need to determine how many cans of paint Jamie needs to buy. Since each can of paint covers an area of 2.5 m², we divide the total area of the table by the area covered by one can:
1.128 m² / 2.5 m² = 0.4512 cans
Since Jamie cannot buy a fraction of a can, he will need to buy 1 can of paint to cover the top surface of the table.
