The area of a regular pentagon is 600 cm Calculate the length of one side of the pentagon?
Area is not measured in centimeter units. It may be guessed that the question should have indicated the area in square centimeters.The area of a regular pentagon is given as:A = s * s * sqr(25 + 10*(sqr(5)) / 4Solve for s:s = 2 * sqr (A / sqr(25 + 10*(sqr(5)))Insert the area of 600 square centimters:s = 2 * sqr (600 cm*cm / sqr(25 + 10*(sqr(5)))s = aproximately 19.67 cm
How many square feet in 9 acres?
392040 sqr ft
What is the distance between point A 000 and point B 345?
I'm assuming that these are 3-D coordinates A(0,0,0) and B(3,4,5) The distance formula between two points in 3 dimensions is the following: D = SQR {(x1-x2)2 + (y1-y2)2 + (z1-z2)2} D = SQR {(0-3)2 + (0-4)2 + (0-5)2} D = SQR {9+16+25} = SQR {50} D is approx. = 7.07
How do you find the length of the base of an isoceles triangle when both sides are 34cm and the height is 30cm?
pythagoreon thereom 34sq - 30sq = 256 sqrt = 16 base 16+16 = 32 half length of base = SQR(34^2 - 30^2) =SQR(1156-900) =SQR(256) =16 base length = 2x 16=32
How many square yards are in a 8 foot diameter?
Pi x D2 / 4 = area ft2 = 3.142*8*8/4 = 50.272 square yard = 9 sqr ft (3*x3) thus 50.272/9 sqr yrds in 8 ft diameter = 5.586
