The area of a sector of a circle of radius cm formed by an arc of length cm is?

Calculated Answer

11.25

Step by Step Solution

In order to solve problem, you must evaluate 1 / 2 * n₀ * n₁.

n₀ =	5
n₁ =	4.5

1 / 2 * n₀ * n₁
Evaluate 1 / 2 = 0.5
0.5 * n₀ * n₁
Evaluate n₀ * n₁ = 22.5
0.5 * 22.5
Evaluate 0.5 * 22.5 = 11.25
11.25
The answer to the problem and the result of 1 / 2 * n₀ * n₁ is 11.25
