Answer:
Area of the gym floor = 100.8 square meters
Step-by-step explanation:
Area of the gym floor = Area of rectangle A + Area of rectangle B - Area of the overlap
Area of rectangle A = 105 square meters
Area of rectangle B = 8.4 square meters
Area of the overlap =
=
= 12.6 square meters
Area of the gym floor = 105 + 8.4 - 12.6
= 100.8 square meters
Therefore, area of the gym floor is 100.8 square meters.
It looks like you want to compute the double integral
over the region <em>D</em> with the unit circle <em>x</em> ² + <em>y</em> ² = 1 as its boundary.
Convert to polar coordinates, in which <em>D</em> is given by the set
<em>D</em> = {(<em>r</em>, <em>θ</em>) : 0 ≤ <em>r</em> ≤ 1 and 0 ≤ <em>θ</em> ≤ 2<em>π</em>}
and
<em>x</em> = <em>r</em> cos(<em>θ</em>)
<em>y</em> = <em>r</em> sin(<em>θ</em>)
d<em>x</em> d<em>y</em> = <em>r</em> d<em>r</em> d<em>θ</em>
Then the integral is
