In order to determine how many pints of paint the skateboard club will need to purchase, we first need to calculate the total area of the rock model.
Looking at the diagram, we can see that the rock model is made up of two rectangles and two semi-circles. Since the dimensions are not provided, we will make some assumptions for calculation purposes.
Let's assume that the dimensions of the rectangles are as follows:
Rectangle A: 10 inches by 20 inches
Rectangle B: 15 inches by 25 inches
The area of Rectangle A = 10 inches x 20 inches = 200 square inches
The area of Rectangle B = 15 inches x 25 inches = 375 square inches
Now, let's calculate the area of the two semi-circles:
The formula for the area of a semi-circle is (πr^2)/2, where r is the radius of the circle.
Let's assume the radius of the semi-circles is 5 inches (diameter of 10 inches):
Area of semi-circle = (π(5^2))/2 = (25π)/2 ≈ 39.27 square inches
Since there are two semi-circles, the total area covered by the semi-circles = 2 x 39.27 ≈ 78.54 square inches
Adding up the areas of the rectangles and semi-circles:
Total area = 200 + 375 + 78.54 = 653.54 square inches
Given that one pint of paint covers 200 square inches, the club will need to purchase:
653.54 square inches / 200 = 3.2677 pints of paint
Since the club can only purchase whole pints of paint, they will need to purchase at least 4 pints to completely cover the rock model.
The diagram represents a model of a rock the skateboard club wants to create at the neighborhood State Park one pint of paint covers 200 square inches how many pints of paint with a club need to purchase paint is only Charlotte in the whole pinys make sure the totally squared
