<span>The cosine of an angle is the quotient of the side that angle lay on and the hypotenuse.</span>
x-hypotenuse
cos45=19/x
0.707=19/x, x=19/0.707, x=26.9
Hypotenuse is <span>approximately 27.</span>
so let's take a circle with radius (r) = 3cm
Area of the circle = πr² = 3.14 × 3² = 3.14 × 9 = 28.26cm²
hope it helps...!!!!
