Answer:
14.13 units^2.
Step-by-step explanation:
The area of a circle is found by doing pi * r^2. In this case, the diameter is 6. 6 / 2 = 3. So, r = 3.
pi * 3^2 = pi * 9 = 9pi.
This is a semicircle, so the area will be half of the whole circle.
9pi / 2 = 4.5 * pi = 4.5 * 3.14 = 14.13 units^2.
Hope this helps!
Answer:
right
Step-by-step explanation:
The side ratios are ...
24 : 45 : 51 = 8 : 15 : 17
These numbers are a Pythagorean triple. The triangle is a right triangle.
__
24² + 45² = 576 +2025 = 2601 = 51² . . . . the Pythagorean theorem is satisfied
Answer:
area of 105° segment = 74.2 in²
Step-by-step explanation:
area of entire circle = πr² = (3.14)(9²) = 254.34 in²
area of 105° segment = (105/360)(254.34) = 74.2 in²
