antiseptic1488 [7]

Given,

Cylinder A has a volume of 6 cubic units

and height =3 units

The radius of cylinder A,

\begin{gathered} r=\sqrt[]{\frac{V}{\pi h}} \\ =\sqrt[]{\frac{6}{3\pi}} \\ =0.8 \end{gathered}

To find the volume of a cylinder B

\begin{gathered} V=\pi r^2h \\ =(3.14)\times(0.8)^2\times(3) \\ =6.03 \end{gathered}

Thus the volume of cylinder B is 6.03

Let ∠Q be an acute angle such that tanQ=0.04. Use a calculator to approximate the measure of ∠Q to the nearest tenth of a degree
Digiron [165]

We have been given that ∠Q is an acute angle such that \text{tan}(Q)=0.04. We are asked to find the measure of angle Q to nearest tenth of a degree.

We will use arctan to solve for measure of angle Q as:

Q=\text{tan}^{-1}(0.04)

Now we will use calculator to solve for Q as:

Q=2.290610042639^{\circ}

Upon rounding to nearest tenth of degree, we will get:

Q=2.3^{\circ}

Therefore, measure of angle Q is approximately 2.3 degrees.
