Answer:
Blank 1: 1 Blank 2: 8 Blank 3: 72
Step-by-step explanation:
What it is basically saying is that 9*8 is equal to 10*8 - 1*8 [Blank 1]. 10 times any number is a friendly number, it all ends with a 0. The question is saying that it is easier to think of a friendly number and subtracting from that. 10 eights - 9 eights is equal to 1 eight. So we take away 1*8=8 from 10*8=80, or in other words, 80-8 [Blank 2]= 9*8=72 [Blank 3].
Are you starting to see what I mean?
Step-by-step explanation:
1. volume of a cylinder = pi x radius squared x height (I wasn't sure which was the radius/diameter)
2. 615.74
3. 1km
4. rearrange formula for volume of the cylinder to get the radius on 1 side. divide both sides by height and pi to leave u with r². then divide by the square root.
formula= r=square root of 3080³/3.14 × 20
5. height = volume/ pi x radius squared
6. 2463.01
7. 28.01
8. 145.955 m
9. 21.01
10. 17
