Answer:88.5ft
Step-by-step explanation:
Let r represent the radius of the smaller circle and R the radius of the larger
circle.
Apply ratios: the radius of the smaller circle to the radius of the larger circle.
r: R = 3 : 7.
I complete rotation = 360 degrees.
1st:
For one complete rotation of the smaller circle, the larger circle is rotated through (3/7)*(360) = 154.3 degrees
2nd:For one complete rotation of the larger circle, the larger circle is rotated through (7/3)*(360) = 840.0 degrees
This is equivalent to (840/360) = 2.3 rotations
Alternatively, use the ratios: The number of rotations = R/r = 7/3 = 2.3 rotations
Hope this helped☺☺
Answer:
The length of the parking lot is 31 yard .
Step-by-step explanation:
Formula
Area of a rectangle = Length × Breadth
As given
A rectangular parking lot has an area of 682 square yards.
The lot is 22 yards wide.
i.e Breadth = 22 yards
Put in the formula
682 = Length × 22
Length = 31 yard
Therefore the length of the parking lot is 31 yard .
