False, they would be called Complementary
Answer:
1134
Step-by-step explanation:
Formula for diameter=2 x r
(π is 3.14)
Formula for area= π x r^2
So all you basically have to do is go backwords with the first one then plug the radius into the second one normally
38/2=19
Now just plug it into your second equation
π x 19^2=1134.11494795
And lastly round that to 1134, easy! :)
3 3/5 * 5/7
Convert the mixed number into a improper fraction.
18/5 * 5/7
Multiply the numerator(18) by the other numerator(5) while multiplying the denominator(5) by the other denominator(7).
Final Answer: 90/35 or about 2.6 *Both answers are equivalent to each other.
7.75+4.50
Then this equals 12.25 ; You gone want to divide this
519.25 \ 12.25 you get $42.38 or $42.39 if you round.
Or 4.50 x 60 is $270
7.75 x 30 is $232 which is closet to $519.25 which will give u $502.50
