Answer 1

This is the full explanation to your question.

Answer 2

Answer:

The area of the track is 1,695.5414012623 m².

Step-by-step explanation:

Inner circle's circumference = 220m

Divide it by pi ( 3.14) = 70.0636942675m ( diameter)

Divide the diameter by 2 = 35.0318471338 ( radius )

Square the radius ( radius × radius )= 1,227.2303136059m

Multiply it by pi ( 3.14) = 3,853.5031847225m²

Outer circle's circumference = 264m

Divide it by pi ( 3.14) = 84.076433121m ( diameter)

Divide the diameter by 2 = 42.0382165605 ( radius )

Square the radius ( radius × radius )= 1,767.2116515875m

Multiply it by pi ( 3.14) = 5,549.0445859848m²

Area of the outer circle= 5,549.0445859848m²

Area of the inner circle= 3,853.5031847225m²

Therefore, area of the track = 5,549.0445859848m² - 3,853.5031847225m² = 1,695.5414012623m² ( Answer)
