The formula to get the circumference is 2πr, π being pi and r being your radius.
Your r is 0.9 since the radius is half the diameter.
2πr = 2 x 3.142 x 0.9
= 5.6556cm
≈ 5.7cm
Answer:
x=-1/2
Step-by-step explanation:
add 2 to both sides
3x=x-1
subtract x from both sides
2x=-1
divide by 2
x=-1/2
<h2><u>Answer (d</u>) :</h2>
These triangles are congruent under the SAS congruence criterion. We can prove it using the following steps :
Given :
In triangle 1 and 2 :
- A side in triangle 1 and a side in triangle 2 are equal.
- Another side in triangle 1 and triangle 2 is equal.
- The angle between the equivalent sides is also equal.
Since the SAS congruence criterion says that two triangles are congruent if two of their sides and one included angle is equal and since these 2 triangles fulfill all of those rules, we can conclude that these triangles are congruent under the SAS congruence criterion.
Answer:

Step-by-step explanation:
We are given that
Initial value problem
, y(3)=4
Substitute the value 
When t=3 and y=4 then
z=3+4=7

Differentiate z w.r.t t
Then, we get



Integrate on both sides


Substitute t=3 and z=7
Then, we get




Substitute the value of C then we get






Hello!
No solutions means that there is two sides that do not equal or math, therefore, your answer would be c. both sides of the equation are not equal to one another.
Enjoy.
