Step-by-step explanation:
The area of the Triangle PQR which is in the circle, is given as 784.25. See the computation below.
<h3>What is a circle?</h3>
Mathematically speaking, a circle is a 2-dimensional shape whose boundaries are round and are equidistant from a fixed center.
<h3>What is calculation of the answer given above?</h3>
The area of ΔPQR is given as ((√3)/4) x QR²
= (√3)/4) x (6√2 - 2√6)²
= 0.43301270189 x (8.48528137424 x 4.89897948557)²
= 0.43301270189 x 1728
Area of ΔPQR = 784.25
