The answer is r=16 you have to square everything
A roundabout of a radius 7 yd laid with a carpet grass. find the area of the roundabout laid with carpet grass
1 answer:
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,

To solve for the longest side, the hypotenuse, you have to use the pythagorean theorem. It will be 10^2 + 9^2 = c^2. 100 + 81 =c^2.
c^2 = 181 so c = sqrt(181).
to find sin of A do opposite/hypotenuse which gives you 9/sqrt(181)
to find cos of A do adjacent/hypotenuse which gives you 10/sqrt(181)
c^2 = 181 so c = sqrt(181).
