Answer:
- The circumference of the circle in term of pi = 10π inches
- The circumference of the circle us 3.14 as pi = 31.4 inches
Step-by-step explanation:
Given
The radius of the circle = r = 5 in
We know that diameter is twice the radius.
so d = 2r = 2(5) = 10 in
<u>Finding the circumference of the circle in terms of pi</u>
Using the formula to find the circumference of the circle
C = dπ
C = 10×π
C = 10π inches
Thus, the circumference of the circle in term of pi = 10π inches
<u>Finding the circumference of the circle using π = 3.14</u>
We know that the formula to find the circumference of the circle
C = dπ
Given
π = 3.14
substituting π = 3.14 to find the circumference of the circle
C = 10×3.14
C = 31.4 inches
Thus, the circumference of the circle = 31.4 inches
Answer:
The number is 20
Step-by-step explanation:
Let the number be x
5(x - 9) = 2x + 15
5x - 45 = 2x + 15
5x - 2x = 15 + 45
3x = 60
x = 60/3
x = 20
Answer:
Lisa is not right.
Step-by-step explanation:
The equation Lisa is solving is x+6=8+x
The solution for the given value will be the value of x.
To solve for x we isolate the x term that is bring both x on one side of the equal sign.
Subtracting x both sides we have:
x-x+6=8+x-x
The x on both sides gets cancel and hence there is no value of x that will satisfy the equation x+6=8+x.
So Lisa solution is not right.
Answer:
From x->-∞, y->-∞
From x->+∞, y->+∞
Step-by-step explanation:
Look at the graph.
As x value get larger, the graph curves upward infinitely, thus positive infinity y values as x value get larger and positive.
As x value get more negative, the graph curves downward infinitely, thus negative infinity y values as x value get more negative.
