Question

A cathedral has a large, circular stained-glass window. A visitor measures the window and calculates that it has an area of 50.24 square feet. What is the window's circumference?

Use 3.14 for ​.

Answer 1

Answer:

25.133

Step-by-step explanation:

area is pi*r^2. divide area by 3.14 and then sqrt to find radius. 6.28*radius= circumference, so 6.28*4=25.133

Answer 2

Answer:

25.12

Step-by-step explanation:

1. Use the formula for the area of a circle to find the radius

$A=\pi r^2$

$50.24=\pi r^2$

$16=r^2$

$\sqrt{16} =r$

$4=r$

2. Use this value to find the circumference

$C=2\pi r$

$C=2\pi 4$

$C=2(12.56)$

$C=25.12$
