4a * 3a = 12a²
4a * -8 = -32a
-6 * 3a = -18a
-6 * -8 = 48
-12a² - 32a - 18a + 48
combine like-terms: -12a² -50a + 48
Area of roundabout = 153.86 yd2
we are given,
radius = 7 yd
Area of circle = π 
= 3.14 × 7× 7
= 153.86 yd2
<h3>
What is the area of circle?</h3>
The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr2, where r is the radius of the circle. The unit of area is the square unit,
