Find the area and the circumference of a circle with radius 5 yd.
Use the value 3.14 for the radius, and do not round your answer. Be sure to include the correct units in your answers.
Area : ________
Circumference: ________
To find the area of a circle, we use the formula A = πr², where A represents the area, π represents the mathematical constant pi (approximately 3.14), and r represents the radius.
Plugging in the given radius of 5 yd, the formula becomes A = 3.14 * (5)².
Evaluating the equation, we find:
A = 3.14 * 25
A = 78.5
Therefore, the area of the circle is 78.5 square yards.
To find the circumference of a circle, we use the formula C = 2πr, where C represents the circumference, π represents the mathematical constant pi (approximately 3.14), and r represents the radius.
Plugging in the given radius of 5 yd, the formula becomes C = 2 * 3.14 * 5.
Evaluating the equation, we find:
C = 2 * 3.14 * 5
C = 31.4
Therefore, the circumference of the circle is 31.4 yards.
