1/2(Base x height) = area. Divide 400 by 20 to get 20, and cut it in half. 10 is the height.

If a cone's volume is 400 cm3 and its height is 8.5 cm what is its radius?
The radius is 6.704 cm
What is the area of a circle with the radius of 20 inches?
Using 3.14 as Pi the area of circle is: 1256.0
Why can't contour lines cross merge or split?
Contour lines are imaginary lines that join points of equal height. Therefore, say, a 300 metre height contour line can never meet a 400 metre height one.
What is the area of a circle with a diameter of 400 miles?
A ≈ 126,000 square miles.
What is the radius of a circle with an area of 400Π cm squared?
A = pi R^2 = 400 pi R^2 = 400 R = 20
What is the height of a triangle with an area of 200 cm 2 and a base?
Yes, all triangles have a base. area_triangle = 1/2 x base x height ⇒ height = 2 x area_triangle ÷ base = 2 x 200 cm2 ÷ base = 400 cm2 ÷ base
What is the base area of a square pyramid when the side is 20 and height 25?
The base area would be 400 square units (m, ft, or whatever they gave you). You don't have to worry about the height because it is only the area of the base. The area of a square is s2, and 202 = 400.
What is the area of triangle with a base 20 feet long and a height of 40 feet?
area of triangle = 0.5 x base x height area = 0.5 x 20 x 40 area = 400 ft2
Which triangle is larger one with sides measuring 200 300 and 400 cm or one with sides measuring 300 400 and 700 cm?
its called a scalene triangle, scalene triangles have 3 different sides to work out area you do base x Perpendicular height divided by 2 the problem is i dont know which side is base of which is hight, to work out the area of a triangle. you have given little information which is not helpful
What would the base and height be if the area of a triangle is 400?
The area of a triangle does not provide enough information to answer the question. The triangle could be thin and tall or broad-based and short and have the same area.
What is the area of 20 width and 20 height?
Area is width * height; therefore area is 20 * 20 = 400
How can you find the area of an isosceles triangle when the base is 40Cm and the edges 25Cm?
You would first need to determine the height of the . To do this, you would make a line in the middle of the base up to the point where the two 25cm edges meet. From your knowledge of A2+B2=C2 (where A=20 B=unkown and C=25) we now know that B2=C2-A2. So, B2= 625 - 400= 225. The square root of 225 is 15. So now we know the height (B) is 15. The area of a triangle is 1/2 * Base * Height. so we have (0.5)*40*15= 300cm2. This is the area.
Ginny is using a box to store stuff the box has a vol of 400 cub in and a base area of 100 sq in what are the dimensions of the box?
The volume of a box is given by the formula V = length(L) x width(W) x height(H). As the base has an area of 100 sq ins then 400 = 100 H : H = 4. If the base is square then the dimensions of the box are L= 10, W = 10, H = 4. If the base is rectangular then the L and W could be any two numbers such that LW = 100. For example 2 x 50, 4 x 25, 5 x 20. Note that the height remains constant at 4 inches.
If a storm window has an area of 400 square inches what is the equation to find the dimensions when the window is 12 inches higher than it is wide x represents height?
area = width times height x = height x-12 = width x (x-12) = x^2 - 12X = 400 x^2 - 12X - 400 = 0 solve for x using quadratic formula X = (12 + SQRT(144 + 1600)) divided by 2 x = 26.88 = height width = x -12 = 14.88
What is the base area of circular pillar is 400 sqm and its volume is 2000 cumcalculate height of pillar in meters?
Haha math killing you too dude? Oh! Before I forget...bring my pants to school tomorrow...I left them in your bathtub after I sharted! Haha
What is the perimiter of a square if its area is 400 meters squared?
well area of a square is length x height or height2 so the length = the square root of 400 (20) so the perimeter is 4 x 20 s so 80
How many gallons of water does a six inch column that is 400 feet deep in the ground hold?
Assuming that the 6-in is the diameter of the column that is 400-ft long. The volume of a cylinder equals the (area of the base)*height = h[pi]r^2 Area of the base equals area of a circle equals [pi]r^2 r is the radius and equals 1/2 the diameter--.5 ft/2 or .25-ft [pi].25^2 equals .19635 *400-ft equals 78.53982ft� There are 7.48051948 US Gallons per cubic foot 78.53982ft� x 7.48051948 = 587.519 gallons (US Liquid)
