If h = 7 then h squared = 49
h = +11 and/or -11
To determine the surface area of a period (right rectangular), there is a unique formula. It is lw+l to the square root of w/2 squared + h squared + w square root of (l/2) squared + h squared. L=Length, W=Width, H=Height.
some math equations: For area of a triangle: A=1/2 b*h. *=Times or multiplication sign. Area of a square or rectangle: A=b*h Area of a circle: A=pi R squared [try writing this one on a piece of paper. Pythagorean Theorem: a squared + b squared=c squared. perimeter: 2b+2h

The equation for a circle of radius r and centre (h, k) is: (x - h)² + (y - k)² = r² If the centre is the origin, the centre point is (0, 0), thus h = k = 0, and this becomes: x² + y² = r²
h
Volume of cylinder- 3.14*r squared*h Volume of cone- 3.14*r squared*h/3 Volume of cube or rectangular prism-w*l*h Volume of pyramid-w*l*h/3
H=9m
v=3.14(r){squared}(h) The formula is pi x radius (squared) x the height.
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
If you know the height and volume of the cylinder than you can find the radius. You also have to know the formula for volume 'V', which is pi multiplied by both the radius 'r 'squared and the height 'h', or V is equal to pi x r squared x h. The height h is equal to the volume divided by the radius squared and pi.

Consider a square with a slightly smaller square just inside, the smaller square being rotated so that the corners just touch the sides of the larger square. The four spaces between the two squares are four exactly equal right angled triangles. If we call the sides of these triangles h=hypotenuse, L=long side and s=short side then we see that the area of the small square is h squared and the area of the large square is (s +L) squared =s squared + L squared +2s x L. The area of the four triangle is (4 x s x L)/2 By simple arithmetic:- the area of the small square (h squared) = The area of the large square minus the area of the four triangles, h squared = s squared +L squared + 2s x L - (4/2 x s x L). The last two terms cancel each other out leaving h squared = s squared + L squared.
