<em>use √(ab) = √a · √b</em>
<em>use (a + b)(a - b) = a² - b²</em>
<em>use √a · √a = a and √(ab) = √a · √b</em>
A= b h = 6 • 6.5 = 39m^2
Answer: 39m^2
We need to know the perimeter to know how to do the question so is there any more details that could help
<span>Area of the base = 3*4 / 2 = 6
</span><span>Area of BOTH bases = 12 sq inches
Area of one face = 3 * 7 = 21 sq inches
</span>Area of 2nd face = 4 * 7 = 28 <span>sq inches
</span>Area of 3rd face = 5 * 7 = 35 <span>sq inches
TOTAL Area = 96 </span><span>sq inches</span>
Answer:
474.5 ft ³
Step-by-step explanation:
<u>1) Find the volume of the cube</u>
where l is the side length
Plug in 9 ft as l
Therefore, the volume of the cube is 729 ft³.
<u>2) Find the volume of the cylinder</u>
where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
<u>3) Subtract the volume of the cylinder from the volume of the cube</u>
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.
I hope this helps!
