Answer:
Option 4 - 
Step-by-step explanation:
Given : In a circle with a radius of 6 ft, an arc is intercepted by a central angle of 3π/2 radians.
To find : What is the length of the arc?
Solution :
Length of an arc is given by:
where r is the radius of the circle, r= 6 ft.
and 
is the angle in radian, 
Substitute the value given in the formula,
Therefore, Option 4 is correct.
The arc of length is
In order for two lines to be perpendicular, their gradients must multiply together to get -1
7*b=-1
7b=-1
Divide both sides by 7
So, the gradient of line b is -1/7
F. An experiment because they are conducting a study and experimenting with a sample different from what is known
Or, is it asking you to subtract the? In that case
5/4 - 3/8 = 7/8
April made 16 baskets and glued 5 to each Flower so it would be
16×5=80
So she used 80 flowers
