7 Sides on a Twenty Pence Coin
Five sides to a pentagon.
it means p = 23 * p = 6you divide both sides by 3 to get the p alone.
If you mean, the perimeter, P(square)=4s P=4x2.750m P=11.000m
7 Sides on a Twenty Pence Coin
12 sides on a fifty cent piece? (Australian)
16=24-p. subtract 16 both sides 0=8-p. add p both sides P=8
A Circle if you mean 2d circle, 3d sphere =P Any continuously curves shape has no sides; ellipse (ellipsoid), cone, hyperbolic paraboloid...
Area of Triangle when the length of the three sides is known: square-root [P * (P-2a) * (P-2b) * (P-2c)] / 4 where P is total perimeter and a, b and c are the lengths of the three sides.
If you mean: p/35.60 = 18/100 then by multiplying both sides by 35.60 the value of p works out as 6.408
