Answer:
1. 18.84 in
2. 56.52 cm
Step-by-step explanation:
The circumference of a circle is the distance around the circle. Its found using the formula C = πd or C=2πr. The variable d represents the diameter or the distance from one edge of the circle to the other through the cent. The variable r represents the radius of a circle or the distance from one edge to the center. Use the formula by substituting a diameter or radius then simplify.
1. C = πd = π(6) = 3.14(6) = 18.84 in
2. C = 2πr = 2(3.14)(9) = 56.52 cm
Equation
Y=P%*X
Y= 25%*75
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 75
Y = 18.75

The formula given in the question for conversion of temperature is
F = 9x/5 + 32
a. When temperature = 0 degrees centigrade, then
F = (9 * 0)/5 + 32
= 0 + 32
= 32 degree Fahrenheit
b when temperature of boiling water = 100 degree Celsius, then
F = (9 * 100)/ 5 + 32
= 900/5 + 32
= 212 degree Fahrenheit
c. When temperature of water is 15 degree Celsius, then
F = (9 * 15)/5 + 32
= 27 + 32
= 59 degree Fahrenheit
Degrees Celsius = (Fahrenheit -32) * 5/9
Degrees Celsius = (-109.3 -32) * 5/9
Degrees Celsius = -141.3 * 5/9
Degrees Celsius = -78.5
Therefore dry ice must be kept at a temperature of < = -78.5 Celsius
