Answer:

C) 38 units2

Step-by-step explanation:

we know that

The surface area of the composite figure is equal to the area of all its square faces

Each face area is one square unit

$SA=2(9)+2(4)+2(6)=38\ units^2$

In the diagram below, the circle has a radius of 25 inches. the area of the unshaded is 500pi in^2Determine and state the degree

Dmitriy789 [7]

$72^{\circ}$

1) In this question, we are going to make use of the formula for the area of that sector, to find the central angle.

2) So, let's write it out an expression involving the area of a circle, the unshaded area, and the shaded one and then plug into that the given data:

$\begin{gathered} A=\frac{\alpha}{360^{\circ}}\times\pi r^2 \\ A_{Unshaded}+A_{shaded}=A_{Circle} \\ 500\pi+\frac{\alpha}{360}\times\pi r^2=\pi r^2 \\ \\ 500\pi+\frac{α}{360}\pi25^2=25^2\pi \\ \\ 500\pi+\frac{125\piα}{72}=625\pi \\ \\ 500\pi +\frac{125\pi α}{72}-500\pi =625\pi -500\pi \\ \\ \frac{125\pi α}{72}=125\pi \\ \\ \frac{72\times \:125\pi α}{72}=72\times \:125\pi \\ \\ \frac{125\pi α}{125\pi }=\frac{9000\pi }{125\pi } \\ \\ α=72^{\circ} \\ \\ \end{gathered}$

Thus, the centra angle of that shaded area is 72º

A square prism and a cylinder have the same height. The area of the cross-section of the square prism is 314 square units, and t

Crank

Answer:

The volume of the square prism is 6.28 times the volume of the cylinder

Step-by-step explanation:

Volume of the square prism = cross-section * height

Volume of the cylinder = cross-section * height

Dividing one volume by the other, and replacing with data:

Volume of the square prism / Volume of the cylinder = 314/50 = 6.28
