I think 1,5 ? Might be very wrong but that’s my guess ♀️
The answer will be similar as 7x20=140 and 7x2000=14000, the answers are the same but x100 as 140x100=14000
20x100=2000
Answer:
7x-9
Step-by-step explanation:
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
