If the radius of a circle is 3.12 inches, what is the approximate area if you use 3.14 for and the area is rounded to the nearest tenth?
Volume of a Circle formula: \(V = \frac{4}{3} \pi r ^{3}\)
\(V = \frac{4}{3} \pi (3.12)^{3}\)
\(V = \frac{4}{3} \pi (30.371328)\)
\(V = \frac{121.485312}{3} \pi\)
\(V = 40.495104 * (3.14)\)
\(V = 127.15462656\)
Round decimal to the nearest tenth:
127.1546256 ⇒ 127.2
Answer: V = 127.2 cubic inches
