Answer:
3.1
4.2
5.2
42
Step-by-step explanation: They’re congruent so just copy what the other triangle has all you had to do was find the radius.
If y varies directly as the square of x, that means that y=k*x^2. Plugging y=100 and x=5 into it, we get 100=k*5^2=k*25. Dividing by both sides, we get k=100/25=4. Going back to the original equation, we now know that y=4*x^2. Plugging 9=x in, we get 4*9^2=4*81=324=y
Answer:
There are 213.36 centimeters in 7 feet.
Step-by-step explanation:
It is given that:
1 inch = 2.54 cm
We have to find centimeters in 7 feet.
We will convert feet to inches.
1 feet = 12 inches
7 feet = 12*7 = 84 inches
Now,
1 inch = 2.54 cm
84 inches = 2.54 * 84
84 inches = 213.36 cm
Therefore,
There are 213.36 centimeters in 7 feet.
with its given value:
