The perimeter of the given circle is 25.1 square cm.
Step-by-step explanation:
- From the given diagram, the radius of the given circle is 4 cm.
- The perimeter of any given circle is calculated by multiplying 2π with the radius. The radius of this circle is 4 cm and it says π = 3.142
- The Perimeter for the given circle = 2π × r = 2 × 3.142 × 4 cm = 6.284 × 4 cm = 25.136 cm. Rounding this off to one decimal 25.136 square cm, the perimeter equals 25.1 square cm.
3m² = 3 - 8m
0 = 3m² + 8m - 3
0 = (3m - 1 )(m + 3)
m = -3, 0.33
I thank its A if not I’m sorry
Answer:
Addition property of equality
Step-by-step explanation:
Given:

We need to find the missing reason in the proof.
Solution:
By solving the above equation we get;
⇒ Given:
Now by adding both side by 'x' we get;

⇒ Addition property of equality

Answer:
this is easy lol firs add 3+9 which will be 12 then 8+1 so its 9/12 and for the second one 12 +9 21 then 8+4 12/21
