EXPLANATION
The circumference of a circle is calculated using the formula:
From the question, the radius of the circle is 10 inches.
We substitute the radius into the formula to get:
Let us multiply out to get:
The question required that we leave the answer in terms of π.
The correct choice is C.
6.040892193 E-4
which equals to
0.000604<span>0892193
move your decimal place 4 units to the left
because it's a negative (E-4), which makes your number smaller
OR
multiply that number by 10^-4</span>
Answer: 140
Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg.
Let the number of toys Oleg has = x
Let the number of toys Sasha has = y
Let the number of toys Dima has = z
Sasha had twice as many toys as Oleg
So y = 2*x= 2x
Dima had 40 more toys than Oleg.
z = x + 40
Oleg, Sasha, and Dima shared 600 toys
x + y + z= 600
We know y=2x and z=x+40
Replace it for y and z
Subtract 40 on both sides
Divide by 4 on both sides
Oleg had 140 toys
