Given:
Area of a sector = 64 m²
The central angle is 
.
To find:
The radius or the value of r.
Solution:
Area of a sector is:
Where, r is the radius of the circle and 
is the central angle of the sector in radian.
Putting 
, we get
Taking square root on both sides, we get
Therefore, the value of r is 
m.
4tan^(2)x-((4)/(cotx))+sinxcscx
Multiply -1 by the (4)/(cotx) inside the parentheses.
4tan^(2)x-(4)/(cotx)+sinxcscx
To add fractions, the denominators must be equal. The denominators can be made equal by finding the least common denominator (LCD). In this case, the LCD is cotx. Next, multiply each fraction by a factor of 1 that will create the LCD in each of the fractions.
4tan^(2)x*(cotx)/(cotx)-(4)/(cotx)+sin...
Complete the multiplication to produce a denominator of cotx in each expression.
(4tan^(2)xcotx)/(cotx)-(4)/(cotx)+(cot...
Combine the numerators of all expressions that have common denominators.
