We know that
length of circumference=2*pi*r
for r=18 cm
length of circumference=2*pi*18--------> 36pi cm
if 2pi radians (full circle)------------------> has a length of 36pi cm
(3/2)pi radians---------------------------> X
X=(3/2)pi*36pi/2pi----------> x=27pi cm
the answer is
27pi cm
199.81 is the answer to your question.
Answer:
1 is 30, 2 is 70, 3 is 5, 4 is 5. It means 5 nickels equals 1 quarter.
Step-by-step explanation:
A nickel is 5 cent. A quarter is 25 cent. So 1 quarter is 5 nickels.
So, 6 quarters is 30 nickels. 14 quarters is 70 nickels.
It cannot be divided but it if you want it in decimal it's 0.78048780 continuous. Basically the answer is the same as it question unless you want it in decimal.
12x+15y=34
2(-6X+5Y)=3
12x+15y=34
-12x+10y=6 = 25y=40 25/40 =0.25 then you plug that back into any original equation and you get the x
