The surface area can be calculated by adding the area of the rectangle and the areas of the two circles.
Rectangle:
Area = height x width = 18 yards x 15 yards = 270 yards2
Circles:
Area = πr2
Radius = diameter/2 = 15 yards/2 = 7.5 yards
Area of one circle = 3.14 x (7.5 yards)2 = 3.14 x 56.25 = 176.625 yards2
Area of two circles = 2 x 176.625 = 353.25 yards2
Total surface area = 353.25 yards2 + 270 yards2 = 623.25 yards2
So, the correct answer is:
623.25 yards2
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.
