Answer: C=14π≈43.98 ft
Step-by-step explanation:
To find the circumference of the circle, we use the equation C=2πr or C=πd. These 2 equations are equivalent because 2r is the same as d, diameter. In this case, we can use C=πd because the problems already gives us the diameter.
C=πd
C=14π≈43.98 ft

Let x = time if working together
then
x(1/5 + 1/6) = 1
x(6 + 5) = 30
11x = 30
x = 30/11
x = 2.7273 hours
or
x = 2 hours and 44 minutes
Answer:
1000
=
125
/65536
Step-by-step explanation:
Rewrite the expression using the negative exponent rule and then Raise
2 to the power of
21
. Cancel the common factor of 32. Combine 125 and 1
/65536
We know that 1 cm = 400 km
Therefore, 22 cm = x
Cross multiply:
(1)x = (400×22)
x = 8800
