Answer:
r= 4 ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the area is
16 pi = pi r^2
Divide each side by pi
16 pi/pi = pi r^2/pi
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
Answer:
<h2>1525.7 square meters, approximately.</h2>
Step-by-step explanation:
Notice that the radius is 28 meters, and the angle of the orange sector is 137°. However, the angle of the blue sector is:
360° - 137° = 223°
The area of a circular sector is
Replacing given values, we have
Therefore, the right answer is the second choice.
Answer:
Step-by-step explanation:
Use the Pythagorean theorem to find the length x of the third side.
x² + 6² = √90²
x² = 90-36 = 54
x = √54 = 3√6
Answer:
x in (-oo:+oo)
x = n/m-k // - n/m-k
k-(n/m)+x = 0
k-(m^-1*n)+x = 0 // - k-(m^-1*n)
x = -(k-(m^-1*n))
x = m^-1*n-k
x = m^-1*n-k
