Answer:
40287600 = B. 4 x
Step-by-step explanation:
<u>We first have to do the multiplication of the numbers given:</u>
19 * 2,120,400
=> 40287600
<u>Now we have to figure out how many digits are after the number 4:</u>
4, 0 2 8 7 6 0 0
7 digits
Meaning that we need an exponent of 7 for it to be in scientific notation, giving us with the answer B. 4 x
Circumference + perimeter =38
x = circumference of circle
find r in terms of x
2
r=x
r=
Area=r^2
so..
A=()^2
=(
)
=
(38-x) is perimeter
then
()^2
+ ()^2
then you graph it and it equals
16.716 cm the circumference of the circle
