Question

A Japanese garden has a circular koi pond in the middle that has a radius of 3 feet.

What is the area of the Japanese garden around the koi pond? Use 3.14 for pi
195.74 ft2
224.00 ft2
252.26 ft2
337.04 ft2

Answer 1

A) 195.74 ft^2

Explanation:

Step 1: Find the area of the whole rectangle by multiplying 14 * 16 (length * width). 14 * 16 is 224.

Step 2: Find the area of the circle. The formula for the area of a circle is pi*r^2. 3 is the radius. Raise 3 to the second power. 3^2 is 9. Multiply 9 by 3.14. 9 * 3.14 is 28.26.

Step 3: Subtract the area of the circle from the area of the rectangle. 224 - 28.26 is 195.74. That's the area of the garden around the koi pond.
