37.68m this is my best guess sorry if it's wrong :)
Volume = area of base *height
20 = pir^2 *h
20 = 3,14*4*h
h = 20/12,56 = 1,59 rounded 1,6
- using the triangle formed by radius,the height of cup and the slant height of cup so we can writing that
tan ß = h/r so tan ß = 1,6/2 = 0,8
tan ß = 0,8 so ß = arctan 0,8 = 38,6 degrees so 39 degrees
hope helped

Answer:
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Step-by-step explanation:
Let r be a ratio useful in determining how much of each ingredient Henry needs:
4/8 of the mix is cement, 3/8 is sand and 1/8 is gravel.
4/8 of the total 120 kg must then be 60 kg made up of cement;
3/8 must then be 45 kg made up of sand; and
1/8 must then be 15 kg made up of gravel
His 55 kg of cement is 5 kg short of the 60 kg he needs.
Answer:
$415.6
Step-by-step explanation:
Given data
Gross weekly pay = $440.00
<em />
<em>Taxes/deductible</em>
Medical insurance = $14.40
Union dues= $10.00
Total deductible= 14.4+10= $24.4
Hence the net pay
= $440-24.4
=$415.6
