Answer:
12.49 = r
13 = r to the nearest cm.
Step-by-step explanation:
The formula to calculate the volume is:
V = π*r^2*h
We know that V = 10291 cm^3 and Height (h) = 21cm
V = π*r^2*h
10291 = π*r^2*21
Divide both side by 21
10291/21 = (π*r^2*21)/21
490.05 = π*r^2
Now divide both side by π
490.05/π = (π*r^2)/π
155.99 = r^2
Now square root both side
√155.99 = √(r^2) Note: square and square root cancel eachother out.
12.49 = r or,
13 = r
Step-by-step explanation:
1. Ratio(White to black) = 12 / [52 - 12]
Ratio(White to black) = 12 / [40]
Ratio(White to black) = 3 / 10 = 3:10
2. Ratio(Blue triangle to all) = 5 / [5+80]
Ratio(Blue triangle to all) = 5 / [85]
Ratio(Blue triangle to all) = 1 / 17 = 1:17
3. Ratio(Circle to all) = 76 / [22+76]
Ratio(Blue triangle to all) = 76 / [98]
Ratio(Blue triangle to all) = 38 / 49 = 38:49
4. Ratio(Yellow triangle to blue) = 18 / 14
Ratio(Yellow triangle to blue) = 9 / 7 = 9:7
5. Ratio(Yellow triangle to blue) = 42 / 6
Ratio(Yellow triangle to blue) = 7 / 1 = 7:1
6.Ratio(Boys to all) = 63 / [27 + 63]
Ratio(Boys to all) = 63 / 90
Ratio(Boys to all) = 7 / 9 = 7:9
Answer:
5
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(x) = 2x -1
f(3) = 2·3 -1 = 6-1
f(3) = 5
