+256 Amanda, Ben, and Carlos share a sum of money. Their portions are in the ratio of 1:2:7, respectively. If Amanda's portion is 20, what is the total amount of money shared?
+781 Amanda's portion is 1/10 of the total, which is $20. Then the total amount is $200.
can anyone help me
605,8=(Pi/1530)²*21000*i
i = 6842 cm^4
ist that right?if yes can you show me the way
+36915 605,8=(Pi/1530)²*21000*i divide both sides by (pi/1530)^2
143685315.3 = 21000 i now divide both sides by 21000
i = 6842.16
