Answer:
90.25π
Step-by-step explanation:
The formula for solving the area of a circle is πr².
r is the radius. We can find the radius by splitting the diameter in half: 19/2 = 9.5.
We can apply the area formula and we get π9.5² and the answer is 90.25π.
Yes if you convert it into a rational number it will be -155/10
Answer:
B) Data
Step-by-step explanation:
Data has to do with numbers.
Yes, if you know that every 1 quart is equal to 4 cups then the ratio is 1:4. To find out how many cups are in 9 quarts, multiply both sides of the ration by 9. The answer would be 9:36, so there are 36 cups in 9 quarts.
