Answer:
1176.5 square feet
Step-by-step explanation:
<em>Let us recall from the following question,</em>
<em>Because fuel tank is a cylinder, the first step to take is get the surface area of this cylinder.</em>
<em>The Surface area of a cylinder = 2. π. r. 2. +. 2. π.</em>
<em>Then,</em>
<em>The given values (h = 50, r = 7/2 = 3.5) as applied from the formula given,</em>
<em>The area Surface a of fuel tank = 1176.5 square feet</em>
Answer:
0.03177
Step-by-step explanation:
Prob (Bld grp) ~ Bin (N, P)
N = 15, P = Prob of success ie 'O' blood type = 0.45
P (BG = 0) for 3 people = (N c X) P^X . (1-P)^N-X
As X = 3. So Prob = (15 c 3) (0.45)^3 (0.55)^12
= 455 (0.091125) (0.0007662)
= 0.03177
