Answer:
THE THIRD ONE
Step-by-step explanation:
the equation: An=A1+d(n-1)
plug in the numbers
X + 5 = 3
Subtract both sides by 5
X = (-2)

❖ 6 + 45 ÷ 3² = 11
Follow order of operations:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
(Note: Multiplication and division can be done in either order as well as addition and subtraction.)
There are no parenthesis in this problem so we skip to exponents. The exponent is 3² which is 3 x 3 = 9.
We then have division. 45 ÷ 9 = 5
Our last step is addition.
Add:
6 + 5 = 11

Formula: SA = 2πr² + 2πrh
h =40 in
Diameter d =12 in.
Radius = r = d/2 = 12/2 = 6 in
SA = 2π6² + 2π*6*40 = 72π + 480π = 552π (in²)
SA = 552π = 552*3.14 = 1733.28 (in²)
Answer: 1733.28.
