Answer:
818.4 ft^2 to the nearest tenth.
Step-by-step explanation:
The area of the shaded segment = the area of the sector - area of the triangle
= (150/360) * π * 27.8^2 - 0.5 * 27.8^2 * sin 150
= 818.4 ft^2.
Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.
a=2πn, for any integer n
Answer:
12.94
Step-by-step explanation:
By the law of sines:
x / sin(35) = 7.9 / sin70
x = 7.9 * sin(70)/sin(35)
= 7.9 * 0.9397 / 0.5736
= 12.94
Answer:
Diameter of the circle = 2√13
Step-by-step explanation:
The radius is calculated by using the formula for calculating the distance between the two points as shown;
R = √(y2-y1)²+(x2-x1)²
Given the coordinates (0, 2) and (3,4)
R = √4-2)²+(3-0)²
R = √2²+3²
R = √4+9
R = √13
Diameter = 2R
Diameter of the circle = 2√13
