The shaded region is actually a sector and the formula for the area of a sector is:
central angle/360 x pi x radius squared, which is basically a fraction of the area of the circle. With this basic background knowledge, all we have to do is substitute the values into the formula.

(80/36) x pi x 81
= 80/4 x pi x 9
= 720/4 x pi
= 180pi cm squared.

Write the phrase "the product of a number v and 15" as an expression.

Oduvanchick [21]

Translating the phrase to a mathematical expression, the equivalent expression is given by:

$15v$

The product of two numbers is the <u>multiplication</u> of these two numbers, hence:
