Since the pool is square, the four sides are equal.
Therefore the length of one side = sqrt(292) = 17.1 to the nearest tenth.
Answer:
A =12.56 units^2
Step-by-step explanation:
The area of a circle is found by
A = pi r^2
We know the radius is 2
A = pi (2)^2
A = 4pi
Using 3.14 as pi
A = 4(3.14)
A =12.56 units^2
Answer:
1570
Step-by-step explanation:
the formula for surface area of a cylinder is:
A= 2πrh + 2πr²
π aka pi = 3.14
r = 10
h = 15
so now plug in the numbers
A = 2(3.14)(10)(15) + 2(3.14)(10²)
A = 942 + 2(3.14)(100)
A = 942 + 628
A = 1570
