So we can use the following digits: 4,5,6,7,8,9
and we need three numbers with 8 digits each. Here are some examples:
1)
45 678 999 (you can also write 45,678,999 for easier reading)
2) 44 456 789 (you can also write 44,456,789 for easier reading)
3)45 678 456 (or 45,678,456)
1st : Find the volume of the rectangular block:
12 × 10 × 20 = 2400 cm^3.
2nd : Find the volume of a cylinder

Where r is radius & h is height.
so:

= 76.02654222 cm^3
Lastly, divide the volume of the rectangular block by the volume of the cylinder
2400 ÷ 76.026 = 31.5679226
You can't round it up so the answer is F) 31
Answer:no it is not equal
Step-by-step explanation:
Answer:
12 which is on C
Step-by-step explanation:
use pathogoras theorem
a^2+b^2=c^2
16^2+b^2=20^2
256+b^2=400
b^2=400-256
b^2=144
b= square root of 144
b= 12
