Answer 1

Answer: 1133.54

Explanation:

The formula of area of a circle: A =
`\pi`r squared

All you have to do is plug the numbers in, so A= 3.14 (19) squared. Solve

19 times 19 = 361, and 3.14 times 361 = 1133.54

Answer 2

Solve for area

A≈1134.11cm²

r Radius

19

cm

Solution

A=πr2=π·192≈1134.11495cm²
