Answer:

The area of the circle is $9 \pi\ units^{2}$ or $28.26\ units^{2}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ units$ ----> the radius is half the diameter

substitute

$A=\pi (3)^{2}=9 \pi\ units^{2}$ -----> exact value

assume

$\pi=3.14$

$A=9(3.14)=28.26\ units^{2}$

Answer:

The volume of a cylinder:

$V \approx 150.796$ $ft^3$

Step-by-step explanation:

To find the volume of a cylinder, you need the this formula:

$V = \pi r^2h$

-Use the given height and radius for the formula:

$V = \pi 4^2 3$

-Then, solve the formula:

$V = \pi \times 4^2 \times 3$

$V = \pi \times 16 \times 3$

$V = \pi \times 48$

$V = 48\pi \approx 150.796$

So, the volume of a cylinder is approximately $150.796$ $ft^3$ .

Solve the equastion for x + 2 1/2 =10

Virty [35]

Answer:

x= 7 1/2

Step-by-step explanation:

Subtract the 1/2 to get it out of the way (whatever you do on one side of the = sign you have to do to the other)

So 10- 1/2= 9 1/2

Subtract the 2 to get it out of the way

9 1/2-2=

7 1/2

Hope it helped :)

Explain why angle is considered a defined term in geometry.

77julia77 [94]

Answer:

An angle is considered a defined term in geometry because defined terms are terms that have a formal definition and can be defined using other geometrical terms.

Angle: Two rays that share the same endpoint, however, the rays take off in different directions. The area in the middle of the two rays is the angle measure.
