Answer:
Area of shaded region = 329.70 cm²
Step-by-step explanation:
Area of a circle = πr²
Area of bigger circle = 3.14 × 11²
= 3.14 × 11 × 11
= 379.94 cm²
Area of smaller circle = 3.14 * 4²
= 3.14 × 4 × 4
= 50.24 cm²
Area of shaded region
= Area of bigger circle - Area of smaller circle
= (379.94 - 50.24) cm²
= 329.70 cm²
Answer:
7/9 or ~77.7778% or 0.777778
Step-by-step explanation:
First you need to find the total amount or marbles.
Next, find the sum of <em>just</em><em> </em>the<em> </em>blue<em> </em>and red marbles.
Now, find the probability by dividing or simplifying the number of blue and red by the total.
- 14/18= <u>7/9</u> OR <u>~</u><u>0</u><u>.</u><u>7</u><u>7</u><u>7</u><u>7</u><u>7</u><u>8</u>
