The answer of sin^2 (pi/4) + cos^2 (pi/4) is √ 2

<u>Step-by-step explanation:</u>

The value of sin^2 (pi/4) = √2/ 2

The value of cos^2 (pi/4) = √2/ 2

=  √2/ 2 +  √2/ 2

=  √2 +  √2 / 2

= 2 √2 / 2

Dividing √2 by 1

= √2

Answer:

0.37 feet.

Step-by-step explanation:

The following data were obtained from the question:

Volume (V) = 4100 ft³

Height (h) = 1.8 miles

Radius (r) =?

Next, we shall convert 1.8 miles to foot.

This can be obtained as follow:

Recall:

1 mile = 5280 ft

Therefore,

1.8 miles = 1.8 × 5280 = 9504 ft

Finally, we determine the radius as follow:

Volume (V) = 4100 ft³

Height (h) = 9504 ft

Pi (π) = 3.14

Radius (r) =?

V = πr²h

4100 = 3.14 × r² × 9504

4100 = r² × 29842.56

Divide both side by 29842.56

r² = 4100/29842.56

Take the square root of both side

r = √(4100/29842.56)

r = 0.37 ft

Therefore, the radius of the hole is 0.37 feet.
