Answer:
406.4
Step-by-step explanation:
When rounding you only look at the number you're rounding and the one before it. In this case it would be the 4 and 3 after the decimal since we're rounding to the nearest cent. If the numbers before the one you're rounding are 0-4 then you leave the number the same. If the numbers are between 5-9 then you add one to the number. Since the number before 4 is between 0-4 you leave it as 4. But if it was between 5-9 then you'd change the 4 to 5.
I cant rly do all the work rn buy if you add them together and set them equal to 180° you’ll get the answer
The angles are complementary.
This means they add to 90 degrees.
(2x + 1) + (x + 5) = 90.
3x + 6 = 90. (Combine like terms)
3x = 84. (Subtract 6 from each side)
x = 28. (Divide 3 from each side)
x = 28
D is correct
C=2pi(r)
Pi=3.14
r=5.5
So C=2(3.14)(5.5)=34.56
So the circumference is 34.56 mi
And the area is A=pi(r)²
So you have
A=3.14(5.5)²
So A=95.03 mi²
So the area is 95.03 mi² and the circumference is 34.56 mi
Hope this helps!
