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
Answer:11 Years Old
Step-by-step explanation:
Well, if you guess and check, if you say jiris’s age is 11, and 11x2 is 22 and 22+11 is 33 and therefore jiris must be 11 years old(pamela is 22 years old)
4.5 litres of fruit punch with 0.5 litres of water.
13.5 /4.5 = 3. Multiply 0.5 by 3 to get 1.5 litres of water. Therefore, 13.5 litres of fruit punch concentrate needs 1.5 litres of water. 13.5 + 1.5 = 15 litres of fruit punch in total.
Answer:
A)4
Step-by-step explanation:
degree measure of the 4 angles of a trapezoid is 360
so
since we have only 2 angles, 360/2
180=125+(14x-1)
180-125=125+(14x-1)-125
55=14x-1
55+1=14x-1+1
56=14x
4=x or x=4
hope this helps!
Answer:
<h2>The standard form: x² + (y + 1)² = 25</h2><h2>The general form: x² + y² + 2y - 24 = 0</h2>
Step-by-step explanation:
The equation of a circle:
(h, k) - center
r - radius
We have the center (0, -1) and the radius r = 5 <em>(look at the picture)</em>.
Substitute:
<em>use (a + b)² = a² + 2ab + b²</em>
<em>subtract 25 from both sides</em>
