Answer:
B
Step-by-step explanation:
Hi,
2πr is the formula for circumference, you know your diameter is 4cm and radius is half of the diameter, so your radius is 2cm.
To find the circumference, you have to multiply 2 by 2 and pie. 2 x 2 is 4. So 4 times pie. B is your correct answer.
I hope this helps :)
Answer:
X ≥ 3.5
Step-by-step explanation:
-2x-6≤1
+6 +6
-2x≤7
-2x/2 7/2
x ≥ 3.5
Since the triangles are similar, then 32 = x+7 those two angles are too
solve for "x"
now using proportions
solve for JK
solve for KG
the scale factor of the perimeter of both triangles is just the same as the ratio of the sides, or
13. you can round decimals when it comes to money
So, the ratio is 15:24
45:72 divided by 3 is 15:24, so the 1st one is good.
then 97.5:156 156/24 is 6.5 and 97.5/15 is 6.5. SO both are accurate.
