Answer:
π
Step-by-step explanation:
Formula for the circumference of a circle
2r(π)
Area of a circle
πr²
2r(π)=x
x/2(π)=r
π(x/2(π))²=Area
π(x²/4(π)²)=Area
(x²/4(π))=Area
(15π)²÷4π=Area
π
Answer:
(-1,2) is domain
Step-by-step explanation:
Bottom = 2x5 = 10ft
Middle = 2x6 ( 4+2) = 12
Top 4x2= 8
10ft+12ft+8ft= 30ft squared
Answer:
S=32.5
W=97.5
Step-by-step explanation:
S=speed of plane in still air
W=speed of wind
-----------------------------------------
3(S+W)=130
6(S-W)=130
-----------------------------------------
S+W=43.33333...
S-W=21.66666...
2S=64.999...
S=32.5(simplified)
-----------------------------------------
32.5+W=130
W=97.5
-----------------------------------------
The answer is 4ab
hope this helps you
