What is the area of a circle whose circumference is \(6 \pi\)?

Explanation

Since \(C=2 \pi \times r\), then \(r = 3\) … \(A=\pi \times r \times r=\pi \times 3 \times 3\) or \(9 \pi\)

Which of the following expressions is a simplified form of \(\left(-2 x^{2}\right)^{4}\)?

If \(\sqrt{a b} = 4\), then what is the value of \(a^{2} b^{2}\)?

What will be the area of a circle whose circumference is \(3 \pi\)?

Which of the following is the GCF of ab, \(a^{3} b\) and \(a b^{3}\) ?
