Answer:
10π
Step-by-step explanation:
A = πr^2
C = 2πr
= 5
- 5 = r
- 2 * 5 = 10
- C = 10π

Solve for x and y
y = 4x+2
y = -2x - 3
<h3><u>Answer:</u></h3> and
Given equations are:
y = 4x+2 --------- eqn 1
y = -2x - 3 ---------- eqn 2
We have to solve both equations and find values of "x" and "y"
Substitute eqn 1 in eqn 2
4x + 2 = -2x - 3
Combine like terms we get,
4x + 2x = -3 - 2
On solving,
6x = -5
Substitute "x" value in eqn 1
Thus and
Answer: 0.8 radians
Step-by-step explanation:
To solve this exercise you must apply the formula shown below:
Where S is the arc lenght, r is the radius of the circle and is the central angle in radians.
Solve for the central angle:
Now, when you susbtitute the value of the arc length and the radius, you obtain that the central angle is:
