Question

What is perimeter and area of this object?

Answer 1

Answer:

Step-by-step explanation:

You have a circle with radius r = 3 ft and a 3-by-12 rectangle.

Area of circle = πr² = 9π ft²

Area of rectangle = 3 × 12 = 36 ft²

Total area = 36 + 9π ≈ 64.3 ft²

Perimeter of circle = 2πr = 6π ft

Perimeter of rectangular projections = 18 ft

Total perimeter = 6π +18 ≈ 36.8 ft
