Answer:
<em>V = π(2.5)²(7)</em>
Step-by-step explanation:
<u><em>Given:</em></u>
<em>A flower vase is in the shape of a cylinder and has a diameter of 5 inches and a height of 7 inches. </em>
<u><em>To Find:</em></u>
<em>which equation could be used to determine the volume, in cubic inches, of the vase?</em>
<u><em>Solve:</em></u>
<em>Formula for cylinder volume: Volume = πr²h</em>
<em>Where,</em>
<em>h represents the height of the cylinder</em>
<em>r represents the radius of the cylinder.</em>
<em>π is a constant whose value is 3.14</em>
<em />
<em>Knowing that:</em>
<em>Diameter = 5 in</em>
<em>Height = 7 in</em>
<em>Radius = 2.5 {Radius is half of diameter so 5/2 = 2.5}</em>
<em>Thus, a equation could be use is:</em>
<em>V = π(2.5)²(7)</em>

Answer:
y = 3x –5
Step-by-step explanation:
for slope-intercept form, y = mx + b
find the slope, m
(-8 -4)/(-1-3) = m
-12/-4 =m
3 = m
Substitute for m and use either coordinate for y and x to calculate b
4 = 3(3) + b
4 = 9 + b. Subtract 9 from both sides
4 –9 = b
–5 = b. Rewrite the equation with the calculated values for m and b
y = 3x –5
Answer:
Approximately 66.4 Meters
Step-by-step explanation:
So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.
Plug in 18.8 for either <em>a </em>or <em>b. </em>Plug in the diagonal 23.7 for <em>c. </em>
<em />
Therefore, the length is 14.4 meters. Now, find the perimeter:
Answer:
A rectangular Prism
52 square units
Step-by-step explanation:
3*4= 12*2= 24
2*4= 8*2= 16
2*3=6*2= 12
24+12+16= 52
The only thing you could really do is reduce the exponent, so id say A. is the answer. Hope i helped :)
