D. 70% because 45/75=0.6 or 60% and 60% doesn't equal to 70%
Hope this helps!!
Answer:
The radius of the circle r=12.
The area of a circle is 144π.
Step-by-step explanation:
The radius of the circle is r where 2πr=24π, r=12.
The area of a circle with radius 12 is
A=πr², A=π12², A=144π.
The temperature changed a total of 14° over the course of 7 hours with an average change of 2° per hour drop.
That function is incorrect.
The correct function is . . . . C(f) = (5/9) (f - 32) .
If a Fahrenheit thermometer reads 52° ,
then a Celsius thermometer should read . . .
C (52) = (5/9) (52 - 32) =
(5/9) (20) = <em>(11 and 1/9)°C</em>.
