False here are extra words tho make 20 words
Answer:
Step-by-step explanation:
Given
4
The 4 can be placed inside the radical by squaring it, that is
4
= 
= 
=
Since they’re in the same place you would do for 4 X -3 equals 115 and take it from there then you would find your answer and you may have to subtract it by 180
20
Explanation:
20 + 4 = 24. Therefore 24-20=4
Pi = 3. Area of a circle = pi×r squared.
R is radius, and the radius of that circle is 11 m. therefore, 3.14×11 squared will give you your answer. Don't forget, exponent before multiplication
11^2 = 121
121×3 = 363 That's the area of the big circle.
Now, 11÷2 gives you the radius of the small circles. you get 4.5
4.5^2 = 20.25
20.25*3 = 60.75
That's the area of ONE small circle. double it and you have the area of 2.
60.75×2= 121.5
Now just subtract the area of the small ones from the area of the big one to find the area of the shaded region.
363-121.5= 241.5
Now, you're done!
