The answer is 21.2 ft²
To do this we need to calculate the volume of the cylinder shaped drum.The volume (V) of the cylinder with height h and radius r is:V = π r² h
We have:π = 3.14r = 1.5 fth = 3 ft
Therefore:V = π r² hV = 3.14 * (1.5 ft)² * 3 ftV = 21.2 ft²
here you go
Answer:
2x + 7y + 37
Step-by-step explanation:
9+2(x+7)+7(y+2)
= 9 + 2x + 14 + 7y + 14
= 2x + 7y + 37
Required number is 17.
<h3>Justification:</h3>
<u>We need to find the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively</u>.
Hence, we need to find the HCF of 3 numbers (398-7), (436-11) and (542-15).
Hence,
- 398 - 7 = 391
- 436 - 11 = 425
- 542 - 15 = 527
Now, you can find the HCF(391, 425, 527) = 17
<u>Hence, the largest number that will divide 398, 436 and 542 leaving remainders 7, 11 and 15 respectively is 17</u>.
