The nearest tenth is still zero. Reason being you have to start from the right, and once you round the far most 9 to the zero it turns to a one which is too small of a number to round up.
Circumference = 2πr
3π=2πr
r=3π÷2π
r=3/2
area of a circle= πr²
=π×(3/2)²
=2.25π
2/3 = 4/6
4÷2 = 2
2/6 = 1/3

Answer:
x = y = 4
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
( multiply both sides by 8 )
8 × cos45° = x , then
x = 8 ×
= 4
The third angle in the triangle = 45° ( sum of angles in triangle )
Then the triangle is isosceles with congruent legs, thus
x = y = 4
