Hello!

To find the surface area of a sphere you use the equation

A = 4 \pi r^{2}

A is surface area
r is radius

Put in the values you know and 3.14 for pi

A = 4 * 3.14 * 1.5^{2}

Square the number

A = 4 * 3.14 * 2.25

Multiply

A = 28.26

The answer is D)28.26in squared

Hope this helps!

Let f be defined as shown on the graph. Which statement is true?
satela [25.4K]
The inverse of f does NOT exist. The reason why is because the function fails the horizontal line test. Recall that the horizontal line test is a test where you try to see if you can pass a single horizontal line through more than one point on the function curve. If you can get the horizontal line to pass through more than one point, then it fails the test. It's very similar to the vertical line test.
