Area of a circle is πr².
Therefore we can get the radius of the great circle (and thus the sphere) by doing √(A / <span>π).
</span>
√(28.6 / <span>π) = 3.017 to 3DP.
</span>
Surface area of a sphere is 4πr².
4<span>π(3.017)</span>² = 114.4 to 1DP
(X+2)(X+10) heres the factored form
We can see that the area of the triangle is: 5.65in².
<h3>What is a triangle?</h3>
A triangle is actually known to be a shape that has three sides, three angles and three vertices. It's also known as a plane shape.
In order to find the area of the triangle, we will use Pythagorean Theorem: c² = a² + b².
Where c = hypotenuse = 6in.
b = 2in.
6² = a² + 2²
36 = a² + 4
a² = 36 - 4 = 32
a = √32
Area of the triangle = ½ × base × height.
Where base = √32
height = 2
Thus: A = ½ × √32 × 2
A = √32 = 5.65in².
