Question

Kylie drew a circle with a diameter of 8 cm. Paige drew a circle with a radius of 3 cm. Approximately how much larger is the area of Kylie’s circle than the area of Paige’s circle? Use 3.14 for mc022-1.jpg and round to the nearest whole number.

Answer 1

Answer: Approximately 21.98cm larger.

Step-by-step explanation: The area of a circle is A = π·r², where r is the radius of the circle.

Kyle's circle has a diameter of 8cm, which means it has a radius of 4cm.

Calculating the area, it is:

A1 = 3.14.4² = 50.24

Paige's circle has a radius of 3cm, so the area will be:

A2 = 3.14·3² = 28.26

To see how much larger:

50.24 - 28.26 = 21.98cm

So Kyle's circle is 21.98 cm larger.
