The surface area can be calculated by adding the surface area of the rectangle (base x height) to the combined surface area of the two circles (πr^2 for each circle).
The rectangle has a base of 15 yards and height of 18 yards, so the surface area of the rectangle is 15 x 18 = 270 yards^2.
The first circle has a radius of 7.5 yards (half of the diameter), so its surface area is π(7.5)^2 = 176.625 yards^2.
The second circle also has a radius of 7.5 yards, so its surface area is also 176.625 yards^2.
Adding these together, we get 270 + 176.625 + 176.625 = 623.25 yards^2.
So, the correct answer is:
623.25 yards squared
Use the image to answer the question.
An illustration shows a horizontal rectangle of height 18 yards with a circle of diameter 15 yards attached to its top left and a circle of diameter 15 yards attached to its bottom right.
Calculate the surface area. Use 3.14 for π .
