Answer:
A
Step-by-step explanation:
So first you need to know the formula for the area of a segment of a circle which is... A = 0.5 × (θ - sinθ) × r²
*make sure that you do this question in RADIANS
You know that θ (the angle) is 90° which is equal to π/2 and the radius is 3, so from here you just plug in numbers to the equation.
A = 0.5 × ( π/2 - sin(π/2)) × 3²
A = 2.5685... sq units = 3 sq units
The value of t is (D) 55/9.

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
- The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.
To find the value of t:
Given -
- (t+5)/(t-5) = 10
- t+5 = 10(t-5)
- t+5 = 10t - 50
- 10t - t = 5 + 55
- 9t = 55
- t = 55/9
Therefore, the value of t is (D) 55/9.
