(One steel rod’s volume) = 3.14 x 4^2 x 20
= 1004.8cm^3
(Used steel) / (One steel rod’s volume) =
(Made steel rod’s number)
The answer is 28
Area = πr². So you have the diameter which is 56 millimeters. And the radius (r) is half the diameter, so the radius would be 28 mm. Square 28 would be 784, multiplied by π would equal 2463.00864mm. Rounded to the nearest hundredth would be 2843.01mm².
Answer: B
Step-by-step explanation:
Answer: Infinitely many
Step-by-step explanation: 2(x-3)=10x-6-8x
2x-6=10x-6-8x
2x-6=2x-6
Since the number before the number in the tenth place (7) is greater than 5 (8), you will be rounding up. So your answer is 9.80
