Estimate the area of the circle and use 22/7 for pie. the circle shows line all the way across measuring 28cm. find area. can someone explain and show your work. tysm

Area of circle:

A = πr²

π = 22/7, or 3.14 (simplified)

'a line all the way across' means a diameter, which is 28 cm. To find the radius, divide the diameter by 2:

28/2 = 14

Plug in 14 (the radius) to r inside the equation:

A = πr²
A = π(14)²

14² = 196

A = π(196)

π = 3.14

A = 196(3.14)

A = 615.44

615.44cm² is the area of the circle

hope this helps
