Answer:
86 cm²
Step-by-step explanation:
Ok, so since 4 circles fit in the square, each circle's diameter must be 10.
Which means the radius of each circle is 5 because 10 ÷ 2 = 5.
Now we can solve for area.
A = πr²
A = 3.14 x 5²
A = 3.14 x 25
A = 78.5 cm²
78.5 cm² is the area of one circle so we multiply that by 4.
78.5 x 4 = 314 cm²
Now we subtract from the area of the square.
20 x 20 = 400 cm²
400 - 314 = 86 cm²
4% is not equivalent to 40%
0.4 is equivalent to 40%. Just move the decimal two places to the right.
2/5 is equivalent to 0.4, which in turn is equivalent to 40%. 2 divided by 5=0.4
The answers are all but 4%
With this question, the distributive property means to distribute each term in the left parentheses to each term in the right parentheses.
= (-5 - c)( -1)
multiply each term in left parentheses by each term in right parentheses
= (-5 * -1) + (-c * -1)
multiply in parentheses; negative times negative equals positive
= 5 + c
ANSWER: 5 + c
Hope this helps! :)
