This is super confusing
Step-by-step explanation:
Answer:
r = 7 cm
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( where r is the radius )
Given A = 154 , then
πr² = 154 , that is
r² = 154 ( multiply both sides by 7 to clear the fraction )
22r² = 1078 ( divide both sides by 22 )
r² = 49 ( take square root of both sides )
r =
= 7 cm
Is their any more information to the question?
D: -2/3
As the x increases by 6 from 6 to 12, the y decreases by 4. Slope is the change in y over the change in x, so it is -4/6 which simplifies to -2/3
The acceleration would be 6 km/hr/s
60 km/hr / 10 seconds = 6 km/hr/s
Hope this helps!
