Answer:
9.9
Step-by-step explanation:
To solve this problem, we first need to know that the whole length of the circunference is related to a central angle of 2pi radians. Then, we can solve using a rule of three to find the radius:
arc of 6.6 -> central angle of 2/3
arc of 2*pi*r -> central angle of 2pi
2*pi*r * (2/3) = 6.6 * 2*pi
r * (2/3) = 6.6
r = 6.6 / (2/3) = 9.9
So the length of the radius is 9.9

Answer:
Given
The area of a rectangle is less than 81 square centimeters
length 9cm
width =x cm
Step-by-step explanation:
Area of rectangle=length ×width
= 9×X
Area of rectangle is less than 81 cm^2
So 9x-81=0
X=81/9
X=9
So the value of xis 9
