One revolution, namely one go-around the circle, is an angle of 2π radians, in radians unit of course.
now, we know the radius is 4 and 1/2 long, so, what is the "arc" made by the 2π radians angle, with that radius?
Explination: ok so to do this you will need to multiply so
-2.5 • 5
whats 2.5 • 5 it equals 12.5
and because the original number "-2.5" has a negative symbol you just go ahead and put that in there with it.
so your answer is -12.5
Answer:
k = 5/3
x = 21
Step-by-step explanation:
Here, we have two similar shapes
The scale factor here would be the ratio of the corresponding similar sides
so we have k as 15/9 = 5/3
To find the value of x
When two shapes are similar, the ratio of the sides corresponding are equal
So we have it that;
x/35 = 9/15
= 15 * x = 9 * 35
15x = 315
x = 315/15
x = 21
Answer:
he was 9 ft in and swam a total of 87 ft total.
Answer:
it would be C
Step-by-step explanation:
A trapiziod equals 360 degrees in total, so 110+110+70 is 290.
the total degrees 360-290 would give you 70 degrees, so C is correct.
