. A circular table has a diameter of 1.2 meters. Jamie wants to paint the top surface of the table. If one can of paint covers an area of 2.5 square meters, how many cans of paint does Jamie need to buy?
*
1 can
2 cans
3 cans
4 cans
3 cans
To calculate the area of the top surface of the circular table, we need to use the formula for the area of a circle: A = πr^2, where r is the radius of the table (which is half the diameter).
Radius (r) = 1.2m / 2 = 0.6m
A = π(0.6)^2
A = π(0.36)
A ≈ 1.13 square meters
Since one can of paint covers 2.5 square meters, Jamie will need to buy 3 cans of paint to fully cover the top surface of the table.
