ANSWER
• Circumference: 18.84 ft
,
• Area: 28.26 ft²
EXPLANATION
The circumference of a circle of radius r is,

In this case, the radius is r = 3 ft and we have to use 3.14 for π,

Hence, the circumference of this circle is 18.84 feet.
The area of a circle of radius r is,

In this case, r = 3 ft and π = 3.14,

Hence, the area of this circle is 28.26 square feet.
Answer:
I think the answer is B, because the value does increase by one
First use Pythagoras theorem to find the remaining length of the base.
Then multiply the base with the altitude and divide that by 2 and you'll get the area
