Answer:
The square root of 222 is an irational number.
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
Answer:
Step-by-step explanation:
Let first group of people take x candies each
and second group of people take y candies each
5x + 7y will be total candies
5x +7y = 239 (needed to find positive solution of x,y)
now take x=38, y =7
or x=31, y= 12
hence lots of possibilities ,so we can not say exactly
cube root on both sides then subtract 7
answer would be (cube rooted)A-7=Z if that makes sense
