Answer:
The length of the ramp is 13 ft according to the Pythagorean theorem but I don't have an idea about the angle incline.. we must trigonometry to find it .
<u>Answer</u>
C. 16 feet
<u>Explanation</u>
The area of a circle is given by the formula:
Area = πr² Where r is the radius of the circle and π = 3.1416
201.0624 = 3.1416 × r²
r² = 201.0624/3.1416
= 64
r = √64
= 8 feet
Diameter is twice the radius.
∴ diameter = 2r
= 2 × 8
= 16 feet
Answer: There are 13464 cubic feet in the lake.
Step-by-step explanation:
Since we have given that
Surface area of lake = 748 acres
Average depth of lake = 18 feet
So, Volume of lake would be
Surface area of lake × Average depth

Hence, there are 13464 cubic feet in the lake.
