Answer:
B
Step-by-step explanation:
Finding the lengths of the legs of the right triangle, we have 6 and 3. (6*3)/2 = 9. Finding the area of the semi-circle we obtain
which rounding to 3.14 as pi, we obtain 3.5325. Adding up the area of the triangle and the semi-circle and the triangle we get 9+3.5325 which equals 12.5325
So, I understand that you one 1/10th, that is one tenth or
so:
*800=
=80
The answer is 80.
I calculated this by dividing both the nominator and the denominator by the same number - this is always allowed. This number is 10.
You didn't include the formula.
Given that there is no data about the mass, I will suppose that the formula is that of the simple pendulum (which is only valid if the mass is negligible).
Any way my idea is to teach you how to use the formula and you can apply the procedure to the real formula that the problem incorporates.
Simple pendulum formula:
Period = 2π √(L/g)
Square both sides
Period^2 = (2π)^2 L/g
L = [Period / 2π)^2 * g
Period = 3.1 s
2π ≈ 6.28
g ≈ 10 m/s^2
L = [3.1s/6.28]^2 * 10m/s^2 =2.43 m
