Question

The size of a bicycle is determined by the diameter of the wheel. You want a 20-in bicycle for your birthday. What is the area of one of the wheels? 385.47 in2 314.16 in2 484.37 in2 345.54 in2

Answer 1

314.16 in²

Explanation:

If the diameter is 20", then the radius is 10" (1/2 the diameter).

Area of a circle is
`\pi r`²

So, π 10² = 100π = 314.16 in²
