Answer:
Depends on which place you're rounding to:
Step-by-step explanation:
Rounded to the tenths place (one number after the decimal point):
x = -6.6, -9.4
Rounded to the hundredths place (two numbers after the decimal place):
x = -6.59, -9.41
Rounded to the thousandths place (three numbers after the decimal place):
x = -6.586, -9.414
I don't think you'd need to round to the ten-thousandths place. If you do lemme know and I'll edit my answer. But you should know if the next digit is 5 or greater like in 15 you'd round up. If it's less than 5, you round down.
Answer:
C = 10π ft
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius )
to find r use the area formula, that is
A = πr² = 25π ( divide both sides by π )
r² = 25 ( take square root of both sides )
r = 
= 5
then
C = 2π × 5 = 10π ft
