What is the area of a circle with a circumference of 50 pie?
2 answers:
The circumference of a circle is 2
r.
If you plug in the numbers, you get 50 : 2r.
Then you divide 50 from 2, the pi's will cancel each other out, and you get 25. Your radius is then 25 units.
The area of a circle isr², and if you plug in the numbers, you get A: (25)².
Then you do the math and the answer would be: 625 units²
If it needs to be in none-pi form, it would be: 1,963.5 units²

Answer:
clay sphere gives more clay for less money
Step-by-step explanation:
Volume of cone=1/3πr^2h
=1/3*3.14*(9^2)*12
=1/3*3.14*81*12
=3,052.08/3
=1017.36 inches^3
Volume of a cyclinder=πr^2h
=3.14*(9^2)*12
=3.14*81*12
=3,052.08 inches^3
Volume of a sphere=4/3πr^3
=4/3*3.14*(9^3)
=4/3*3.14*(9^3)
=4/3*3.14*729
=9,156.24 / 3
=3,052.08 inches^3
Clay cone=$12
Clay cyclinder=$30
Clay sphere=$28
Which is the best to buy
Comparing volume
Volume of sphere=3,052.08 inches^3
Volume of cyclinder=3,052.08 inches^3
Volume of cone=1017.36 inches^3
Sphere and cyclinder both have the same volume which is 3 times more than volume of a cone
Clay sphere cost $28 which is cheaper than clay cyclinder at the same volume.
Therefore, clay sphere gives more clay for less money
