Answer:
47.1 cm
Step-by-step explanation:
The circumference of a circle is denoted by C = 2πr, where r is the radius.
Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:
C = 2πr
C = 2 * 3.14 * 7.5 = 47.1
To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.
Thus, the circumference is 47.1 cm.
Answer:
y=14x-12
Step-by-step explanation:
in the standard format y=mx+b, m is the slope and b is the y-intercept, so this equation would be y=14x-12 since the slope is 14 and the y-intercept is -12.
Answer:
192x^4+304x^3+36x^2−135x−54
Step-by-step explanation:
Answer:
0.30 miles per min.
Step-by-step explanation:
After 15 minutes a train has moved 4 1/2 miles toward its destination
find;
How many miles per minute is the train moving?
velocity = distance / time
= 4.5 miles / 15 min
= 0.30 miles per min.
Well, no, 2:4 and 5:6 are not equivalent because let’s say if we drew 2:4 and 5:6 as a pizza, then 2:4 is 50% while 5:6 is 83%.
