Ellipse area = PI * a * b
ellipse area = 3.14 * 8 * 7
ellipse area = 175.84
Answer:
Step-by-step explanation:
x = 180 - 80 - 55 (Interior angles of a triangle add up to 180 degrees so if we need to find any unknown angle, we'll subtract all the other angles from 180)
x = 45 degrees
Answer:
80π
Step-by-step explanation:
Circle O with radius IO:
large radius = IO = 12 = R
Circle O with diameter JK
IJ = JK = KL = 2 × IO = 24
IJ = JK = KL = 24/3 = 8
small radius = 8/2 = 4 = r
The shaded area is a semicircle of radius 12 minus a semicircle of radius 4 plus two semicircles of radius 4.
That is the same as
1 semicircle of radius 12 plus 1 semicircle of radius 4
A = πR²/2 + πr²/2
A = π(12² + 4²)/2
A = 160π/2
A = 80π
Equivalent fraction:
5.3125 = 53125/10000 = 85/16 = 5 5/16
Approximate value(s):
5.3125 =~ 5 1/3 (error = 0.392157%)
5.3125 =~ 5 (error = -5.882352%)
y = 0x + 3
switch x and y and solve for y if possible
x = 0y +3
x = 3
Not a function because it doesn't pass the vertical line test .
