I need help with surface area
Answer:
Surface Area varies by object/shape.
Ask your teacher/learning helper for those formulas of surface area
Step-by-step explanation:
Surface area is the sum of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Answer:
24cm
Step-by-step explanation:
Assuming sides AC and BC are equivalent:
AC = 3cm + 9cm = 12cm
BC = AC = 12cm
AB = 3cm + 3cm = 6cm
AB + BC + AC = 12cm + 12cm + 6cm = 24cm

A new experimental tank is in the shape of a cone, cylinder and sphere. All of the tanks have a volume of 10,000 cm3 . One condition to this tank is that the Radius should be 10 cm. Follow up the questions below based on this scenario.
Find the height of cylinder . Keep the answer in terms of π
Answer:
100/π cm
Step-by-step explanation:
Volume of a cylinder = πr²h
Volume = 10,000cm³
Radius = 10cm
The formula for the height of a cylinder is obtained as:
V = πr²h
h = V/ πr²
h = 10000 /π × 10²
h = 10000 /π × 100
h = 100/π cm
The height of the cylinder in terms of π = 100/π cm
The volume of a cube is 216 cubic feet. What is the length of each side of the cube?

Answer:
find the cube root of 216 to get the length of one side as you get the volume of a cube by length x length x length
Step-by-step explanation:
the the cube root of 216 is 6
so the length of one side is 6 inches

Points are plotted at (-2, 2), (-2, -4), and (2, -4). A fourth point is drawn such that the four points can be connected to form a rectangle. What is the area of this rectangle?
Answer:
The area of the rectangle is 24.
Step-by-step explanation:
The given points:
a) (-2, 2)
b) (-2, -4)
c) (2, -4)
To complete the rectangle the other point must be (2, 2), so the rectangle formed has the following dimensions:
x: distance in the x-direction (from -2 to 2):
[tex]x = 2 - (-2) = 4[/tex]
y: distance in the y-direction (from -4 to 2):
[tex]y = 2 - (-4) = 6[/tex]
The area of the rectangle is:
[tex] A = x*y = 4*6 = 24 [/tex]
Therefore, the area of the rectangle is 24.
I hope it helps you!
The center is (3,-2), and a point in the circle is (23, 19)
Answer:
Circumference is about 182.21
Step-by-step explanation:
Use the distance formula to find the radius of the circle with the two coordinates given. The radius of this circle is 29. Plug 29 into the formula 2(pi)r to find the Circumference. The answer is 182.21
The equation of the circle is [tex]\rm(x-3)^2+(y+2)^2=29^2[/tex].
What is the equation of circle?The equation of the circle is given by;
[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]
Where r is the radius and h and k are the centre of the circel.
The radius of the circle is;
[tex]r=\sqrt{(23-3)^2+(19-(-2))^2} \\\\r=\sqrt{(20)^2+(21)^2} \\\\r=\sqrt{400+441}\\\\r =\sqrt{841}\\\\r=29[/tex]
The equation of the circle is;
[tex]\rm (x-h)^2+(y-k)^2=r^2\\\\\rm (x-3)^2+(y-(-2))^2=29^2\\\\ (x-3)^2+(y+2)^2=29^2[/tex]
Hence, the equation of the circle is [tex]\rm(x-3)^2+(y+2)^2=29^2[/tex].

Answer:
14.4in so your radius is your third answer
Can someone please help me with this
Answer:
Step-by-step explanation:
5- There are 2 right-angled triangles and 1 equilateral triangle or you can just say triangles
6- area for a triangle is a=bh(1/2)
so 4×3=12(1/2)=6
and 4×3=12(1/2)=6
In both triangles, they're a=6
7- 4×6=24(1/2)=12
the top flag is a=12
8-12+6+6=24
9- the rectangular flag has an area of 24 since a=bh and the added areas of the triangles are 24. I conclude that these are two ways of finding the area of this rectangular flag.
hope this helps : )
