Answer:
y=10.4
Step-by-step explanation:
If you mean Y instead of x then the answer is 10.4
3.8+y=14.2
-3.8 -3.8
y=10.4
Answer:
C =131.88 cm
Step-by-step explanation:
We can find the circumference of a circle by using
C = pi * diameter
C = 3.14 * 42
C =131.88 cm
Answer:
option B and D, I believe.
Step-by-step explanation:
In option B its times itsself
in option D it is x times y (y=5)
Part A:
Circumference = πd
Circle A: d = 7
7π = 21.98
π = 21.98/7 = 3.14
Circle B: d = 6
6π = 18.84
π = 3.14
Part B:
Area = πr^2
Circle A: r = 3.5
π3.5^2 = 38.465
12.25π = 38.465
π = 3.14
Circle B: r = 3
π3^2 = 28.26
9π = 28.26
π = 3.14
Part C: The value of π is the same in circles A and B
