Aiguo places 6 circular biscuits, each with the same diameter, on a baking sheet as shown below. What is the approximate area of the baking sheet left uncovered? Please hurry!

46cm²

Step-by-step explanation:

Find the diagram attached.

The area of the baking sheet left uncovered = Area of rectangle - Area of the 6 circular biscuits

Area of the rectangle = Length * Width

Given

Length = 12cm

Width = 18cm

Area of the rectangle = 12*18

Area of the rectangle = 216cm²

The diameter of one of the circle = Length/3

The diameter of one of the circle = 18/3 = 6cm

Area of a circle = πd²/4

Area of a circle = π(6)²/4

Area of a circle = 36π/4

Area of a circle = 9π cm ²

Area of the six circular biscuit = 6(9π) = 54πcm²

Area of the six circular biscuit = 54(3.14) = 169.56cm²

Area of the baking sheet left uncovered = 216 - 169.56

Area of the baking sheet left uncovered = 46.44cm²

Area of the baking sheet left uncovered is approximately 46cm²
