X is always dependant to Y. so that should answer the 1st one. the 2nd looks to be around 17-18. 17.5 maybe. and the 3rd is yes cause he does not go to the pool so it isnt any cost.
Answer:
Let R = radius of big circle
r=radius of small circle
A1=Area of small circle
A2=Area of big circle
R=9r
A1=50cm^2
A1=pi*r*2
A2=pi*R^2
A2=pi*(9r)^2
A2=81*pi*r^2
A2=81*A1
A2=4050cm^2
Hence the big circle has area of 4050cm^2
Step-by-step explanation:
For this question, we need the formula τ = F x d<span>, and just plug the numbers in.
</span>
Given the formula <span>τ = F x d</span>
Where τ = torque,
F = force applied, &
d = distance from the axis / hinge,
<span>τ = 300 c 0.8 = 240Nm</span>
Disregard the weight of the door or if there's any friction at the hinge. None of this will change the torque applied.
