These are the two answers you could get
<span>Hmm, divide 67.50 by 9, that'll give the how much it is /pizza. </span>
To find r, you need to isolate it. pi*r^2*60=18,840. divide 18,840 by 60, then pi, it comes out at 100. Now find the square root to get 10
r=10
Answer: 200cm
Step-by-step explanation:
The center Planck is a square of length 8cm.
The 4 next planks are of 16 cm each
And the next 4 Planks are of 32 cm each.
8 + 4(8×2) + 4(8×4)
8 + 4(16) + 4(32)
8 + 64 + 128
200 cm
Length of the original plank is 200cm
Solve for z
3z+4=34
Subtract 4 from both sides.
= 3z=30
Divide both sides by 3
z=10
Hope I helped! :D
