Find the circumference and area of a circle that has a radius of x+1

Circumference: 2πr

Circumference: 2 (3.14) (x + 1)

Circumference: 6.28 (x + 1)

Circumference: 6.28 (x) + 6.28 (1)

Circumference: 6.28x + 6.28

Area: πr²

Area: 3.14 (x + 1) ²

Area: 3.14 (x + 1) (x + 1)

Area: 3.14 (x (x + 1) + 1 (x + 1))

Area: 3.14 (x (x) + x (1) + 1 (x) 1 (1))

Area: 3.14 (x² + x + x + 1)

Area: 3.14 (x² + 2x + 1)

Area: 3.14 (x²) + 3.14 (2x) + 3.14 (1)

Area: 3.14x² + 6.28x + 3.14
