Answer:
radius = 5
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here r² = 25 ( take the square root of both sides )
r = = 5
|2x+5|-4=16 find both answers

Answer:
122°
Step-by-step explanation:
The measure of the central angle is twice the measure of the inscribed angle that subtends the same arc.
∠ABC = 2×∠ADC = 2×61°
∠ABC = 122°
Answer:
<u>Given:</u>
- Diameter of rug = 6 feet
To find the area of the rug, we need to use the formula "πr² or π(D/2)²"
<u>Where:</u>
- r = radius
- d = diameter
Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.
