The answer for this will be letter d. C = 22π and A = 121π. This is computed using the formula of C= Dπ which is C = (22)π. On the other hand, the area of this circle is computed by using the formula A = <span>πr^2. This is computed as follows:
A = </span><span>πr^2
A = </span><span>π (22/2)^2
A = </span><span>π (11)^2
</span>A = 121<span>π</span><span>
</span>
Answer:
not similar
Step-by-step explanation:
similar means proportional
1, 1, and 0.5 are not proportional to 3.5, 3, and 2.25

Step-by-step explanation:
Given,
Total tickets = 1172,
In which every ticket costs $ 2, also, three prizes will be awarded 1 for $ 500, 1 for $250 and 1 for $125.
Thus, we can make a table that represents the given situation,
Number of tickets 1 1 1 1169
Probability of ticket 1/1172 1/1172 1/1172 1169/1172
Price of ticket $ 500 $ 250 $ 125 - $ 2
( Note : Negative sign shows the loss, i.e. if we could not get any price then we have a loss of $ 2 )
Thus, the expected value of a ticket
Hi
area of circle, which is call in proper math terme circumference ( latin for going around) is given by this formula :
2 times radius x pi
As math is all about knowing your formula and training, I let you have a shot. You wont progress other wise.
