Answer:
314.16
Step-by-step explanation:
Area=πr2
d=2r
Solving for Area
A=1
4πd2=1
4·π·202≈314.15927
There are 146 - 84 = 62 girls
ratio is 84:62
simplifies to 42:31
45/45/90 triangles have side lengths leg/leg/leg root2
Here the leg is root 7 and the x is in the hypotenuse so x is root 7 * root 2
Simplifies to root 7*2 = root 14
1. true
2. true
3. true, because the absolute value can never be negative..
4. false ( if wrong then the question wasnt that specific to me, sorry)
5. true...
if im wrong you have the right to be mad, but to me I feel 90% right about the answers...sorry
