Answer:
Step-by-step explanation:
Given that a car mechanic rounds a car's weight to the nearest thousand
By rounding off to nearest 1000, we mean we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.
To simplify the above we can say the 100th digit if greater than or equal to 5, we round off the 1000th digit by 1 up otherwise leave it as it is
Example, 18765 is rounded off as 19000 while
15462 is rounded off as 15000
Here the answer after rounding off is 4000
This is possible if the weight was atleast 3500 because in this case he would round off to 4000 or highest 4499.
If 3499 or 4500 the rounding off would not have been 4000
So least number is 3500 and greatest number is 4499.
Answer:
Total volume = (145/3)π in³
Step-by-step explanation:
First find the volume of the entire cylinder. The correct formula to use here is:
V = πr²h, where r is the radius and h is the height. Here, with the radius being 5/2 inches and the height being 8 inches, the cylinder volume is
V = π(2.5 in)²(8 in) = 50π in³
Next find the volume of the conical shape: V = (1/3)π(2.5 in)²(0.8 in)
The desired volume is equal to the volume of the entire cylinder LESS the volume of the cone:
π(2.5 in)²(8 in) = 50π in³ LESS (1/3)π(2.5 in)²(0.8 in), which simplifies as follows:
Total volume =
50 π in³ - (1/3)π(2.5 in)²(0.8 in), or
(2.5 in)²π[8 in - 0.8/3 in] = π(6.25 in²)(8 in - 8/30 in) = π( 6.25 in²)(116/15 in), or
Total volume = (145/3)π in³
Answer:
1/2 of a Foot
Step-by-step explanation:
There are 12 inches in a foot. So the equivalent of 6 inches in feet would be 1/2 a foot.
