Find the area of a circle with a radius of 8. Either enter an exact answer in terms of pie or use 3.14 for pie and enter your answer as a decimal

64π

Step-by-step explanation:

The area of a circle can be found using the formula:

A=πr^2

The radius is 8, so we can plug that into the equation.

A=π(8)^2

Simplify.

A=64π

Or, as a decimal:

A=64*3.14

A=200.96

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
