Area of a Circle: A = πr²
Step-by-step explanation:
*Note: A semicircle is <em>half</em> a full circle.
<u>Step 1: Define</u>
Radius <em>r</em> = 10 cm
<u>Step 2: Solve for </u><em><u>A</u></em>
- Rewrite Area of Circle Formula: A = 0.5πr²
- Substitute in <em>r</em> [Area of Semicircle Formula]: A = 0.5π(10 cm)²
- [Area] Evaluate exponents: A = 0.5π(100 cm²)
- [Area] Multiply: A = 50π cm²
Answer:
D) 4x=85, x=21.25
Step-by-step explanation:
If the total is 85$, and every shirt costs the same amount, then you would divide 85 by 4.
