Answer:
175.84 m
Step-by-step explanation:
Given that:
A circular garden which has a radius of 28 m.
= 3.14
To find:
The fencing required to enclose the circular garden ?
Solution:
Here, we are given a circle and its radius.
We are required to find the perimeter of the circle in order to find the fencing required to enclose the circular garden..
Formula for finding the perimeter of a circle is:
Perimeter = 
where
is the radius of the circle.
Using the given values in the formula:
Perimeter =
= <em>175.84 m</em>
Therefore, 175.84 m of fencing is required.
Answer:
x greater than or equal to 3
x greater than or equal to -8/3
Step-by-step explanation:
It can be both because there are diffrent sizes
Weight of man and paint = 160 + 5 = 165 total pounds.
Gravitational force is independent of the path taken so we can ignore the radius of the silo.
Work done = total weight x height
The problem says he climbs to the top so overall height is 90 feet
Work = 165 lbs x 90 ft = 14,850 ft-lbs
