Answer:

510.25 cm².

Explanation:

First, your gonna need to find the radius before continuing

80.1 ÷ 3.14 = 25.5

25.5 ÷ 2 = 12.75

Find the area

A=πr²

12.75² = 162.5

162.5 × 3.24 = 510.25

Answer: The area is 510.25 cm². If the circumference of the cap were smaller then the area would be smaller as well

Step-by-step explanation:

First, you must find the radius

80.1 ÷ 3.14 = 25.5

25.5 ÷ 2 = 12.75 <---- radius

Then from that, you find the area

A=πr²

12.75² = 162.5

162.5 × 3.24 = 510.25

Hope this was helpful!
