2*pi*R should be substituted in. 2*13*3 = 78
Mass divided by volume = density... I dont know the exact answer but i hope this helps
Hello,
x=5 cos t and y=5 sin t are the parametric equations of the circle of center (0,0) with radius=5
x²=25*cos²t
y²=25*sin²t
x²+y²=25(cos²t+sin²t)
==>x²+y²=25
Step-by-step explanation:
Create an equation such that x equals the decimal number.
Count the number of decimal places, y. Create a second equation multiplying both sides of the first equation by 10y.
Subtract the second equation from the first equation.
Solve for x.
Reduce the fraction.
Answer:
x = 1/25
Step-by-step explanation:
Solve for x:
25 = 1/x
25 = 1/x is equivalent to 1/x = 25:
1/x = 25
Take the reciprocal of both sides:
Answer: x = 1/25
