Answer:
942 6/7 cm²
Step-by-step explanation:
Since O = Center of bigger circle, OA = Radius of bigger circle.
∴ Area of smaller circle - Area of bigger circle = Area of shaded part.
∴ Area of smaller circle = 22/7 × 10²
= 22/7 × 100
= 2200/7
= 314 2/7 cm²
∴ Area of bigger circle = 22/7 × 20 ²
= 22/7 × 400
= 1257 1/7 cm²
∴ Area of shaded part = 1257 1/7 - 314 2/7
= 942 6/7 cm²

Step-by-step explanation:
<u>Step 1: Define</u>
3x² - 4(2y - 4/12) + 8
x = 6, y = 2
<u>Step 2: Evaluate</u>
- Substitute in variables: 3(6)² - 4(2(2) - 4/12) + 8
- Evaluate exponents: 3(36) - 4(2(2) - 4/12) + 8
- Multiply: 108 - 4(2(2) - 4/12) + 8
- (Parenthesis) Multiply: 108 - 4(4 - 4/12) + 8
- (Parenthesis - Fraction) Simplify: 108 - 4(4 - 1/3) + 8
- (Parenthesis) Subtract: 108 - 4(11/3) + 8
- Multiply: 108 - 44/3 + 8
- Subtract: 280/3 + 8
- Add: 304/3
Answer:
4.9%
Step-by-step explanation:
6600 * 107/100 = 66*107 = 7062.
3500 * 101/100 = 35x101 = 3535
7062+3535=10597. Original worth: 10100
10597-10100 = 497
497/10100 = 0.0492079208, or 4.92%, rounds to 4.9%
