I need help with this did I get this right
Scrat [10]
You’re very close! This is a triangular prism which means that the triangle portion has a unique formula. In order to find area of the triangle you do (base x height) and then divided by 2. In this case, base=6 and height=5 so 6x5=30 and 30 divided by 2 is 15. Then multiply by the length which is 10. The final answer is 150cm cubed.

A hollow ball is made of rubber that is 1 centimeter thick. The ball has a radius of 5 centimeters at the outside surface.
serious [3.7K]
Given that the ball has a thickness of 1 cm and the radius at the outside is 5 cm, thus the radius from inside is 5 - 1 = 4cm.

The <span>approximate volume of rubber used to make the ball is given by the volume of the ball at the outside surface minus the volume of the ball at the inside surface.

i.e.
</span>
<span>Volume\ of\ rubber= \frac{4}{3} \pi\left(5^3-4^3\right) \\  \\ = &#10;\frac{4}{3} \pi(61)= \frac{244}{3} \pi\approx255.5\ cm^3</span>

What is the common rule for simplifying a negative exponent with a coefficient?<br> Ex: 3^-1
rjkz [21]
Anything to a negative power becomes the inverse with the coefficient to a positive power.
For example, 3^-1 becomes 1/3^1 or just 1/3.
3^-2 would be 1/3^2 or 1/9.
