We know that
[the area of a circle]=pi*r²
for r=4 ft
[the area of a circle]=pi*4²------> 50.24 ft²
if 2π radians ( full circle) has an area of-----------------> 50.24 ft²
5π/2 radians--------------------------------------> X ft ²
X=(5π/2)*50.24/2π-------> 62.8 ft²
the answer is
62.8 ft²
Answer:
The correct option is D)
.
Step-by-step explanation:
Consider the provided cubic function.
We need to find the equation having zeros: Square root of two, negative Square root of two, and -2.
A "zero" of a given function is an input value that produces an output of 0.
Substitute the value of zeros in the provided options to check.
Substitute x=-2 in
.

Therefore, the option is incorrect.
Substitute x=-2 in
.

Therefore, the option is incorrect.
Substitute x=-2 in
.

Therefore, the option is incorrect.
Substitute x=-2 in
.

Now check for other roots as well.
Substitute x=√2 in
.

Substitute x=-√2 in
.

Therefore, the option is correct.
