Area of circle = πd²/4, where d = diameter
= π*6*6/4 = 9π ≈ 9 *3.1416 ≈ 28.2744 cm²
Area ≈ 28.27 cm²
Hope this explains it.
Answer:
D. 60°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relationship of interest is ...
Sin = Opposite/Hypotenuse
sin(M) = ON/OM = 4(√3)/8 = (√3)/2
M = sin⁻¹((√3)/2) = 60°
If you add $300 and $600 and you spent 1,300. you would have 2,200 dollars left in all.
Answer:
5.97
Step-by-step explanation:
If the radius of the circle = r then
pi r^2 = 56
r^2 = 56/pi
r = sqrt(56/pi)
The radius of the circle is equal to half of a diagonal of the square. That is,
r = (1/2) sqrt (2x^2)
= x (sqrt 2)/2
= x/(sqrt 2)
So x = r sqrt 2
= sqrt (56/pi) sqrt 2
= 4 sqrt (7/pi)
= 5.9708
