Answer: -8

Explanation: If g(x) = x² + 2x - 8, then g(-2) = (-2)² + 2(-2) - 8

which simplifies to 4 + (-4) - 8 or 0 - 8 which is -8.

Find the area of the circle <br><br> r = 6 ft
Andru [333]

If the radius of the circle is 6 feet. Then the area of the circle will be 113.097 square feet.

<h3>What is a circle?</h3>

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

The radius of the circle is 6 feet.

Then the area of the circle will be

Area = πr²

where r is the radius of the circle. Then we have

Area = π × 6²

Area = 36π

Area = 113.097 square feet

More about the circle link is given below.
