Answer:
1) 18^2 = 324
324 x 3.14 = 1,017.36 in2
2) half of 25 is:
12.5
12.5^2 = 156.25
156.25 x 3.14 = 490.625 m2
Answer:
ax^2 + bx + c
Step-by-step explanation:
The standard form of an equation of a parabola is ax^2 + bx + c
a and b are coefficients and b is a constant
A parabola opening up has a positive a value while a parabola opening down has a negative a value
The product in scientific notation is 8*10^2

How to multiply and divide in scientific notation?</h3>
Here we want to find the product between 4*10^6 and 2*10^6, and write that in scientific notation.
First, we can solve the direct product:
(4*10^6)*(2*10^6) = (4*2)*(10^6*10^6)
Here we used the fact that we can multiply in any order we want.
Now we will use the property:
a^n*a^n = a^{n + m}
(4*2)*(10^6*10^6) = 8*10^{6 + 6} = 8*10^12
The correct option is the second one, counting from the top.
