Answer:
Take out the area of the full circle first:
A= pi r^2
A= 3^2 x pi
A= 28.274 cm3
Area of smaller cirlces:
A= pi r^2
A= 1^2 x pi
A= 3.14159
Multiply by 2 as 2 circles: 6.28318
Substract unshaded from shaded: 28.274-6.28318
Area of shaded is 21.99082 cm3
Step-by-step explanation:
25c - 5
Simplify all of the answer choices & see which one is correct.
a) 5(5c - 1)
25c - 5
A) IS CORRECT.
b) 5(20c + 1)
100c + 5
B IS INCORRECT.
c) 5(5c)
25c
C IS INCORRECT.
d) 5(c -1 )
5c - 5
D IS INCORRECT.
Therefore, the correct answer is a) 5(5c - 1)
