Answer: 50.24 m2
Step-by-step explanation:
the fomlua for the area of a cuculal is
A=1/4 π d^2
so...
1/4 * π * 8^2
=50.24
Answer:
Please check the explanation.
Step-by-step explanation:
We know the equation
y = kx
k = y/x
where k is the proportionality constant
so,
First ratio can be calculated as
Miles = 45
Hours = 3/4
The ratio = 45 / (3/4)
= (45 × 4) / 3
= 180/3
= 60
Thus, the proportionality constant = 60
Thus, the remaining ratios can be calculated as:
The Pair (135, Hours)
135/Hours = 60
Hours = 135 / 60
= 27/12
= 9/4
= 2.25
Thus, the pair is (135, 2.25)
The Pair (Miles, 3)
Miles/3 = 60
Miles = 60×3
= 180
The Pair (90, Hours)
90/Hours = 60
Hours = 90 / 60
= 3/2
= 1.5
Thus, the complete table:
Miles 45 135 180 90
Hours 3/4 9/4 3 3/2
Verification:
Miles / Hour = 45/(3/4) = 60
Miles / Hour = 135 / 2.25 = 60
Miles / Hour = 180 / 3 = 60
Miles / Hour = 90 / 1.5 = 60
Answer:
A , C, D
Step-by-step explanation:
Check A:
8 - 3 + 4 + 21 = 30 30 > 10 , so they keep the ball
Check B:
30 - 7 - 8 - 12 = 3 3 < 10 , so they don't keep the ball
Check C:
2 + 16 - 5 - 3 = 10 10 = 10 , so they keep the ball
Check D:
5 - 2 + 20 - 1 = 22 22 > 10 , so they keep the ball
Check E:
20 - 3 - 13 + 2 = 6 6 < 10 , so they don't keep the ball
