To solve the problem, we need to get the formula for area of a circle -
Area   = pi * r^2; r= radius
           = 3.14 * (13cm)^2
           = 3.14 * 169cm^2 or 3.14 * 13^2cm^2
           = 530.66cm^2
Therefore, the area of the circular plate is 530.66cm^2

olchik [2.2K]

Answer: Kayla used 2 5/24 cups of paint all together.

Step-by-step explanation:

Kayla paints a bookcase by using

1 5/6 cups of paint on the outside of the bookcase. Converting 1 5/6 cups to improper fraction, it becomes 11/6 cups of paint.

She also used 3/8 cup of paint on the inside.

Therefore, the total number of cups of paint that Kayla used all together would be

11/6 + 3/8 = (44 + 9)/24 = 53/24 cups of paint. Converting to mixed fraction, it becomes

2 5/24 cups of paint
