Step-by-step explanation:
If you are trying to find the total number for angles than add 90 and multiply it depends on what math your doing
Here’s the answer and how i worked it out step by step. hope this helps :)
Given,
Time taken by motorboat to going 200 miles upstream is 5 hours.
Time taken by motorboat to going 200 miles downstream is 4 hours.
At upstream,
The speed of boat is offosed by the speed of current.
At downstream,
The speed of boat is incraesed by the speed of current.
Consider,
The speed of boat is b.
The speed of current is c.
The speed is calculated as,
Similarly,
Substituting the value of b from equation (2) then,
Substituting the value of c in equation (1) then,
Hence, the speed of boat is 45 mile per hour and speed of current is 5 mile per hour.

Answer:
Brad needs 37.68 ft of plastic edging to enclose the flower garden, in terms of "pi" it is 12π only.
Step-by-step explanation:
Given:
Diameter of the circular flower garden = 12 ft
We have to find the measure of the plastic edging Brad need to have.
So,
We have to find the length of the edge of the circular garden for circular object the measure of its length has a special name we call it circumference.
And it is very well known to us that:
For any circle the ratio of its circumference and its diameter is equivalent to pie (π) which is equal to 3.14
Then,
⇒
In the above question we have to find the measure of its circumference.
⇒
⇒
⇒ ft
⇒ Or
⇒
⇒ ft
Brad needs 37.68 ft of plastic edging to enclose the flower garden, in terms of "pi" it is 12π only.
