Question

A company makes steel lids that have a diameter of 13 inches. What is the area of each lid? Round your answer to the nearest hundredth

Answer 1

Answer:

132.73

Step-by-step explanation:

the equation for area of a circle is A=πr*2

if your diameter is 13 simply take half of that and plug into the equation

π(6.5)*2 which when put into a calculator comes out to 132.732289

Answer 2

The answer is 132.665 rounded is 132.67

area= r2 × π
13÷ 2 = 6.5
6.5 × 6.5 = 42.25
42.25 × 3.4 = 132.665 ------> 133.67
