Answer:
0.3 in²
Step-by-step explanation:
This picture is NOT to scale. That 20° Angle looks more like 70°.
Area of the circle = 81pi = 254.469
20/360 of the circle = 1/18 = 14.137
Area of triangle = 13.851
14.137-13.851= 0.3 in²
Answer:
Base is 6 m or 6000mm or 600cm
Step-by-step explanation:
A meter is 1000 mm or 100cm
The height of the triangle is 4 meters
The area of the triangle is 12 meters²
The formula for the area of a triangle is:


<em>Divide both sides by 4</em>

<em>Multiply both sides by 2</em>

<u>The base of the triangle is 6</u>
Its either a or c im not entirely sure which one but I do know it has to be in parentheses.
