Question

Evaluate the expression for the given values. \(3.14 r^{2},\) where \(r=0.25\) inches

Short answer

Answer: The value of the expression is \(0.19625\).

Step-by-step solution

Substitute the given value of r into the expression

Replace \(r\) in the expression \(3.14 r^{2}\) with the given value of \(0.25\) inches: \(3.14 \cdot (0.25)^{2}\)

Evaluate the expression

Calculate the expression: \(3.14 \cdot (0.25)^{2} = 3.14 \cdot 0.0625 = 0.19625\) So, the value of the expression \(3.14 r^{2}\) is \(0.19625\) when \(r=0.25\) inches.
