Answer:
508.68 in^2
Step-by-step explanation:
The equation given: 2πr^2+2πrh
Givens: r = 3 in, h = 3*8 in = 24 in, π ≈ 3.14
Substitution: 2(3.14)3^2+2(3.14)3*24
Solution: 508.68
Answer: I don’t see any lines
Step-by-step explanation:
Answer:
2826 inches^2
Step-by-step explanation:
The general formula for the total surface area of a regular pyramid is
T.S.A.=12pl+B
Where p represents the perimeter of the base, l the slant height and B the area of the base.
The perimeter of the base is.
p=2L+2W
P=2*10+2*9
P=20+18
P= 38 inches
The area of the base is.
B=10*9
B=90in^2
T.S.A.=12(38)(6)+90
T.S.A=2736+90
T.S.A=2826 inches^2
Hence the paper needed is 2826 inches^2
The probability that the combination starts with 2 is 1/3
<h3>Probability</h3>
Probability is the likelihood or chance that an event will occur.
Probability = expected/total outcome
The total outcome = 3! = 6
The expected outcome if the combination starts with 2 is given as 2! = 2
Pr(the combination starts with 2) = 2/6 = 1/3
Hence the probability that the combination starts with 2 is 1/3
