2016年5月2日 · Her current height is 168 cm. How tall was she one year ago? Algebra. 1 Answer Alan P. May 2, 2016 #160 ...

2016年12月17日 · Surface Area: 168 sq.cm. Volume: 120 cu.cm. Here is the prism as I believe it has been described: The hypotenuse length of 10 is calculated based on the Pythagorean Theorem: sqrt(6^2+8^2) Since we were asked to use a perimeter construct in calculating the surface area, we might note that the vertical surface area is: "perimeter of right-triangular base" xx "prism height" =24xx5 =120 The total ...

2017年2月4日 · 332.55 Let L, and H be the sides and the height of the equilateral triangle, respectively. As can be seen from the diagram. the height is perpendicular to the base. By Pythagorean theorem, we know that : L^2=(L/2)^2+H^2 => L=sqrt(4/3)H=2/sqrt3H Area A=1/2BH, where B is the base and H is the height. For an equilateral triangle, B=L Given H=24 => A=1/2*2/sqrt3*24*24=332.55 (2dp) Alternative ...

2015年3月22日 · The webpage explains how to find the rate at which the volume of a cone changes with respect to its radius using implicit differentiation and the product rule.

2016年11月20日 · 168 sq feet Number of square feet of tiles needed to cover the area of a room would be equal to the area of the room. In the present case, the area of the room is 14x12= 168 sq feet. This 168 square feet of tiles would be needed.

2017年9月6日 · #r = "5 cm" -># the radius of the cone; #h = "2 cm" -># the height of the cone; Plug your values into the equation to get. #V = 1/3 * pi * "5 cm"^2 * "2 cm"# #V = "52.36 cm"^3# Now, to find the density of the material, you must determine the mass of exactly #"1 cm"^3# of material. To do that, use the fact that #"52.36 cm"^3# of material have a ...

2016年10月26日 · The formula for area of a parallelogram is A = b xx h. A = b xx h 150 = 6(4x- 3) 150 = 24x - 18 168 = 24x x = 7 So, the base measures 4(7) - 3 = 25 inches. Let's draw a diagram. So, we need to find a in order to find the perimeter. We can visualize a parallelogram as a square with two triangles on the side. The square, in this case, has a side length of 6 inches. So, the right triangle on the ...

2016年10月18日 · A cone has a height of #6 cm# and its base has a radius of #4 cm#. If the cone is horizontally cut into two segments #3 cm# from the base, what would the surface area of the bottom segment be? Geometry Perimeter, Area, and Volume Perimeter and Area of Non-Standard Shapes

2016年2月18日 · The polygon will have 40 sides. The measure of the interior angles of a polygon is determined by the formula ((n - 2)180)/n = interior angle measure were n is the number of angles and sides of the polygon. We know that the interior angles of the polygon in the question have measures of 171^o ((n - 2)180)/n = 171^o ((n - 2)180) = 171^o(n) 180n - 360 = 171n -360 = 171n-180n -360 = -9n -360/-9 ...

2017年11月7日 · Let the height of the triangular shaped garden be h yards. Its base would then be 5+h yards. Formula for the area of any traingle is #1/2# base X height. By this formula, #1/2# (5+h) Xh= 168. On simplifying this. #h^2 +5h =336# Or #h^2 +5h-336=0#. Now factorise this quadratic expression by splitting the middle term, keeping in view the fact ...
