Answer:
10,995.6 ft^3.
2300.3 gallons.
(both to the nearest tenth).
Step-by-step explanation:
Area of the surface of the river = area of the outer circle - area of the inner circle.
Radius of the outer circle = 30 *3 = 90 feet.
So the surface area of the river = π(90)^2 - π(85)^2
= 875π ft^2
Also the volume of the river = surface area * depth = 875π*4 = 3500π ft^3
= 10,995.6 ft^3.
Number of gallons of water it will hold = 10,995.6 / 4.78
= 2300.3 gallons.
The radius would be 10 and the arc would be 5.
I hope this helps.
Have a blessed day!
Answer:
Answer:
h = \frac{2A}{b}
Step-by-step explanation:
Given
A = \frac{1}{2} bh
Multiply both sides by 2 to clear the fraction
2A = bh ( isolate h by dividing both sides by b )
h = \frac{2A}{b}
Answer:
The total number of trees the farmer planted = 1056 trees
Step-by-step explanation:
It is given that,
A tree farmer Planet 3 types of trees on 22 acres of land and,
he planted 48 trees per acre
<u>To find total number of plants</u>
There are 22 acres of land.
In one acre he planted 48 trees.
Therefore total number of plants in 22 acers = 22 * 48 = 1056 trees
$208
Steps:
10% of 130 is 13
13 x 6 would give you 60%
13 x 6 is 78
60% = 78
130 + 78 = 208
