Answer:
The area of a circle with a circumference of 18.84 is 28.26 units²
Step-by-step explanation:
Given:
Circumference = 18.84
Let R be the Radius of a Circle
pi = 3.14
To Find:
Area of Circle = ?
Solution:
We Know that,
Substituting the values we get the radius
Now Formula for calculating Area of Circle is given as
Substituting the Radius we get
The area of a circle with a circumference of 18.84 is 28.26 units²
Answer:
(1 , 2
)
Step-by-step explanation:
Given the 2 equations
7x - y = 7 → (1)
x + 2y = 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the y- term
14x - 2y = 14 → (3)
Add (2) and (3) term by term to eliminate y
15x = 20 ( divide both sides by 15 )
x = =
= 1
Substitute this value of x into either of the 2 equations and solve for y
Substituting in (2)
+ 2y = 6
2y = 6 - =
( divide both sides by 2 )
y = = 2
