To convert radians to degrees, make use of the fact that pi<span> radians equals one half circle, or 180º.</span>
<span>This means that if you divide radians by </span>pi, the answer is the number of half circles. Multiplying this by 180º will tell you the answer in degrees.
<span>So, to convert radians to degrees, multiply by <span>180/</span></span>pi, like this:
Degrees= radians X 180/pi
<span> </span>
Answer:
Step-by-step explanation:
general equation for a circle at the origin is
x² + y² = r²
if the circle center is (x₀, y₀), the formula is
(x - x₀)² + (y - y₀)² = r²
(x - 8)² + (y - 10)² = 36
Answer:
1149.8 m³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ( r is the radius )
Here diameter = 13, thus radius = 13 ÷ 2 = 6.5
V = × 3.14 × 6.5³
= × 3.14 × 274.625
= 
≈ 1149.8 m³ ( to the nearest tenth )
