The radius of the circle is 35 cm
Step-by-step explanation:
One revolution of the wheel of a cart = the length of the circumference of the wheel
Let the radius of the wheel be r cm
The circumference = 2 X pi X r
In 5000 revolutions the wheel covers 2 X pi X r X 5000 cm
According to the problem,
2 X pi X r X 5000 = 11 X 1000 X 100
or, pi X r = (11 X 1000 X 100)/(2 X 5000)
or, r = 110 / pi
or, r = (110 X 7)/22
= 35
Here is the answer.
Answer:
43 mph
Step-by-step explanation:
1 day = 24 hours
3 days = 3 × 24 hours = 72 hours
The car taveled 3106 miles in 72 hours.
average speed = distance/time
average speed = (3106 miles)/(72 hours)
average speed = 43 mph
the answer is a because the +2 is the why intercept.
Answer:
6
Step-by-step explanation:
The ratio of 
is a constant
= 
= 
= 
That is y = x
When x = 21, then
y = × 21 = 6
Hello :
An = A1×q^(n-1)....A1 =1 and q = 1.5
An = 1×(1.5)^(n-1)
An =(1.5)^(n-1)
