If a circle has a diameter of 16 feet, which expression gives its area in square

Biology
1 answer:
bagirrra123 [75]3 years ago
6 0

Answer:

The options are unclear but the answer is 8^2π square feet or 64π sqfeet

Explanation:

Area of a circle is denoted by: πr^2 where r is the radius of the circle.

In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2

= 16/2 = 8 feet.

Thus, the radius = 8 feet.

Hence, Area of a circle = πr^2

= π × 8^2

= 64π or 8^2π sqfeet.
