A circle has a radius of 3.88 inches. Using the correct number of significant digits, find the circumference and area of the circle. The circumference is in. The area is in.

The circumference of the circle is 24.37 in

The area of the circle is 47.27 in²

Step-by-step explanation:

The circumference of a circle is given by the formula

Where is the circumference of the circle

is a constant (Take = 3.14)

and is the radius of the circle

From the question,

radius, = 3.88 in

Hence, the circumference, becomes

in

Hence, the circumference of the circle is 24.37 in

For the area of the circle,

Area of a circle is given by

Where is the area of the circle

Since, radius, = 3.88 in

The area of the circle then becomes

in²

Hence, the area of the circle is 47.27 in²

the answer would be 44.79
