Answer:
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
Answer is a :
100 + 300% of 100 = 400

Step-by-step explanation:
Answer:
Least: ![\sqrt[6]{64}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7B64%7D)
2nd least: (
)²
2nd greatest: 
·
Greatest: 1/64^-2
Step-by-step explanation:
= 2
()² = 64
· = 9 · 9 = 81
1/64^-2 = 4,096
Answer:
69
Step-by-step explanation:
All the given arcs cover the entire circle circumference, so their measures add up to a full 360.
(2x - 16) + (x + 40) + x + 60 = 360
4x + 84 = 360
4x = 276
x = 69
