Answer:
Arc length = 9.42 cm
Step-by-step explanation:
First you need the circumference of the circle
r = 6
C = 2* pi * r
C = 2 * 3.14 * 6 = 37.68
To find the length of the arc, we need to know the central angle. IN this case it is 90 degrees (notice the right angle of the triangle).
To find the length of the arc Arc length = (central angle in degrees/360) * C
Arc length = 90/360 * 37.68
Arc length = 9.42 cm
Answer:
A) 3
Step-by-step explanation:
The notation f(x)=[x] represents the greatest integer function, with the integer being less than or equal to x.
Since we have to find the nearest integer smaller than the given number, we can say that greatest integer function always rounds down its input to the nearest integer.
We have to find the value of [3.6]. So we have to round down 3.6 to its nearest integer, which will be 3.
Therefore, the option A gives the correct answer.
I agree with the person that commented first
Your answer should be 93 because 7 times 7.5 is 52.5 and 9 times 4.5 is 40.5 40.5+52.5=93!
