Answer:
- <u>Area of circle is 379.94 feet²</u>
Step-by-step explanation:
<u>Given:</u><u> </u>
- Radius of circle = 11 feet
<u>To </u><u>Find:</u><u> </u>
<u>Solution</u>:
Here given that radius of circle is 11 feet. Using the formula of area of circle we will get the required area of circle
<u>On substituting the required values: </u>
Area = 3.14 × (11)²
Area = 3.14 × 121
Area = 379.94 feet²
Hence,
- <u>Area of circle is 379.94 feet²</u>
Answer:
80
Step-by-step explanation:
25/100 is one fourth so flip the fraction then multiply by 20 for your answer
Identity: sec^2(x) = 1 + tan^2(x) => tan^2(x) = sec^2 (x) - 1
sec(x) = √[37/6] => sec^2 (x) = 37/6
tan^2 (x) = 37/6 - 1 = 31/6
tan (x) = +/- √[31/6]
Given that sin (x) is negative and sec (x) is positive, we are in the fourth quadrant, so the tangent is negative, then:
tan (x) = - √[31/6] = - 2.27
