The correct answer is A: 3. This is because...
3 * 4 = 12
12 * 5 = 60
Therefore, the answer is 60.
C=2πr=π/2
2πr=π/2
4πr=π
r=π/4π=1/4
A=πr^2=(1/4)^2*π=1/16*π

Answer:
The correct answer is first option
X = 34.61
Step-by-step explanation:
<u>Points to remember</u>
<u>Trigonometric ratios</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see that a right angled triangle with base x and hypotenuse = 81.9.
One angle = 65°
To find the value of x
We have Cos θ = Adjacent side/Hypotenuse
Cos 65 = X/81.9
X = 81.9 * Cos 65
= 81.9 * 0.4226
= 34.61
Therefore X = 34.61
The correct answer is first option
3/1 - 3/8 = 21/8
SIMPLIFIED= 2 and 5/8
2 and 5/8 is your answer.
