Step-by-step explanation:
Diameter =12 ft
i.e 2r=12
or, r=12/2 =6ft
SA =3πr²
=3(6)²π ft²
=3×36π ft²
=108π ft²
Answer:
Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.
This is the order you use when you need PEMDAS. For example, in this question:
(2 * 3) + 5(3)
First, you solve the parenthesis: 2 * 3 = 6
Next, you solve for multiplication: 5(3) = 15
Finally, you add: 6 + 15 = 21

Answer: 8
Step-by-step explanation: the given expression is 2n-3
so when n=1, we will get, 2(1)-3=2-3=-1
when n=2, we will get, 2(2)-3= 4-3=-1
when n=3, we will get 2(3)-3= 6-3=3
when n=4, we will get 2(4)-3 = 8-3=5
so the required result of expansion is -1+1+3+5=8
answer is 8.
