<span>the formula that I used would be
p = a √( 2 - 2 cos(A) ) = a √( 2 + 2 cos(B) )q = a √( 2 + 2 cos(A) ) = a √( 2 - 2 cos(B) )<span>p2 + q2 = 4a2
this would give us these measurements for the diagonals
p=9
q=15</span></span>
Surface area of the cylinder = 2 pi r * 40 = 2 pi * 3* 40 = 24 pi
of the cone this is pi * 3 * 5 = 15pi
of the hemisphere this is 1/2 * 4 * pi * 3^2 = 18pi
So the answer is 24pi + 15pi + 18pi = 57pi = 178.98 cm^2
2 because the square root is 12 and the distance is 12 units
Answer:
$1,300
Step-by-step explanation:
commission on the first $10,000
= 4/100 * 10000
= $400
remaining amount
= $28,000 - $10,000
= $18,000
commission on remaining $18,000
= 5/100 * 18000
= $900
total commission
= $400 + $900
= $1,300
A fraction is a short way to write a division problem.
Every fraction means (the top number) divided by (the bottom number).
When you actually do the division, you get the decimal.
3 divided by 5 = 0.60 .
To change any decimal to a percent, you move
the decimal point two places that way ==> .
0.60 = 60% .
