Answer:
radius = 21
circumference = 138.88
Step-by-step explanation:
First divide the area by 3.14, this equal 441
441 is your radius squared.
Then you have to find the root of 441 which is 21.
radius = 21
diameter = twice the radius or 2 * radius
diameter = 21 * 2 = 42
diameter = 42
Then plug 42 in your circumference formula.
Which is then C = 3.14(42).
Which means the circumference is 131.88.
Answer:
The answer is -4x^2
Step-by-step explanation:
-3x^2 - 5x^2 + 4x^2
= -3x^2 + -5x^2 + 4x^2
Combine like terms:
-3x^2 + -5x^2 + 4x^2
(-3x^2 + -5x^2 + 4x^2)
= -4x^2
Total - book $ - magazine $
Which is equal to:
Total + (-book $) + (-magazine $)
$35 + (-$7) + (-$5)
ANSWER: (C) $35 + (-$7) + (-$5)
Hope this helps! :)
