You should have the formula for area. Area = length x width Length = 196 Width = 96 Area = 196 x 96 Do the math, check with a calculator. 9,342 otherwise.

i dont think u need the height here.... in not quite sure though. but circumference is 2(pi)*r. so.... if c=2(pi)r then r=c/2(pi) = 100cm/ (2*3.14) =100cm/6.28 =15.9cm (pi) represents 22/7 or 3.14 i dont have d symbol here n im 2 lazy 2 go get it. hope i helped

lw = 35 (w + 16)w = 35 w^2 + 16w - 35 = 0 Use the quadratic formula to solve (found here http://www.glogster.com/media/4/18/25/75/18257533.gif ) Make sure to use exact values. It will end up with... -8 ± 3√(11) Now you can use either one to solve (what I mean by...

l = 10

**cm**w = 5**cm**h = x V = 250**cm**^3 if V = l * w * h then h = V / (l*w) h = 250 / (10*5) h = 5**cm**B ------ I'm not the greatest with factoring, but...3 Answers · Education & Reference · 13/08/2011

The formula for the volume of a sphere is πr³ (pi times the radius cubed). The radius of the sphere is half the diameter, or in this case 7. So the formula with substitution is: π7³ π343 1077.56537 1078cm³ Check out...

If you cannot use sine or cosine then this means you must use tangent. By the acronym SOH CAH TOA, this means that tan(theta)=opp/adj. So, you must find the missing length of this triangle to solve this problem (Pythagorean s...

Well, the formula for a sphere's volume is V=4/3*pi*r^3 Next step is to plug in the numbers and solve exponent. V=4/3*3.14*20^3 V=(4/3*3.14)*8000 V=4.18666666667(repeating number)*8000 V=33493 1/3(fraction would be exact) or you...

Divide the base in two, and you have two right triangles. The base is 5cm, the hypotenuse 10cm. Use Pythagorean's theorem to solve for the height.
