Area of larger circle: 3.14 x 5^2 = 78.5
Area of small circle: 3.14 x 2^2 = 12.56
Difference of the 2 areas: 78.5 - 12.56 = 65.94
Probability of being in large circle but not small circle: 65.94 / 78.5 = 0.84 = 84%
The answer is A) 84%
Answer:
to the right of zero if postive if negative left
-6 is the answer that you want
Answer:
The length of BC would be 12.2 mm.
Step-by-step explanation:
Given,
In triangle ABC,
∠BAC = 90°,
Thus by the Pythagoras theorem,
We have,
AB = 9.6 mm and CA = 7.6 mm,
By substituting the values,
Step-by-step explanation:
Using the formula for the area of a triangle we can solve for the base.
The formula for area of a triangle is : Area = 1/2 x base x height
We are given the area and the height:
33.6 = 1/2 x 4 x base
Multiply both sides by 2 to remove the 1/2:
67.2 = 4 x base
Divide both sides by 4 to solve for the base:
67.2 /4 = 16.8
Check: Area = 1/2 x 4 x 16.8 = 33.6
The base is 16.8 inches.
