Answer:
The circle length is 90*pi which should be 3.14
So the circle length is 282.6
The central angle is 90 degree which is 1/4 part of 360 degree
From the theory of arc, the arc length should also be 1/4 part of circle length.
So the answer should be 1/4 * 282.6 = 70.65
Becasue it should be to the nearest tenth, so the answer should be 70.7
Step-by-step explanation:
Find the average of all the tests on the first and second test. You find the average by adding up all the test scores and dividing it by the number of test scores you added. Then you can see if she did better than the overal average on each of the tests

- [Right Triangles Only] Pythagorean Theorem: a² + b² = c²
Step-by-step explanation:
<u>Step 1: Identify Variables</u>
Leg <em>a</em> = <em>x</em>
Leg <em>b</em> = 2
Hypotenuse <em>c</em> = 7
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute [PT]: x² + 2² = 7²
- Isolate <em>x </em>term: x² = 7² - 2²
- Exponents: x² = 49 - 4
- Subtract: x² = 45
- Isolate <em>x</em>: x = 3√5
- Evaluate: x = 6.7082
- Round: x ≈ 6.7
