Question

Express the area of each figure as a monomial.
Solve 7x^4 if the formula is s^2.

Answer 1

The figure given was a circle with a radius = 7x^4

Area of a circle = π r²

Area of a circle = 3.14 * (7x^4)²
Area of a circle = 3.14 * 7² * x^(4*2)
Area of a circle = 3.14 * 49 * x^8
Area of a circle = 153.86x^8
