Answer:
Circumference of Circle B=19.625cm
Step-by-step explanation:
The circumference formula is: 2pie(r) = pie(d)
We have diameter of the first circle which is 6. Now, because the diameter of second circle is 25% greater than this,
Hence, we add 25% in 6:
6+25/100 =6+0.25=6.25 cm
Therefore, we have diameter of 6.25 for circle B.
Now, we need to find the circumference of the Circle A.
circumference= pie(d) = pie(6)= 3.14times6= 18.84
Now use the proportional reasoning to find Circumference of Circle B:
circumference of Circle A/diameter Circle A = circumference of Circle B/diameter Circle B
18.84/6=circumference of Circle B/6.25
Cross multiply and divide:
(18.84times6.25)/6 = Circumference of Circle B
Solve:
Circumference of Circle B=19.625cm

<h3>Solve the equation. Then check your solution. </h3><h3>1.6a = -9.12 </h3>
Answer: b) -5.7
Step-by-step explanation:
<em>To solve this equation for the variable a, we have to clear the variable a, dividing both sides of the equation by the coefficient of the variable a. </em>
a = -9.12/1.6 = -5.7
Answer: b) -5.7

Answer:
54-28=26-32=6
Step-by-step explanation:
54-28=26
32-26=6
The unit rate would be:
180 mi/3h
=60 mi/h
Therefore the unit rate would be 60 miles per hour
