Question

10 jeometre formulas ​

Answer 1

1.a 2 + b 2 = c 2

2.Area = sqrt [ s(s - a)(s - b)(s - c) ] , where s = (a + b + c)/2.

3.Perimeter = 2L + 2W

4.Pythagora's theorem: The two sides a and b of a right triangle and the hypotenuse c are related by. a 2 + b 2 = c 2

5.Circumference = 2*Pi*r. Area = Pi*r 2

6.Arclength: s = r*t.

7.Volume = L*W*H.

8.Surface Area = 2(L*W + H*W + H*L)

9.Area = (1/2) *r 2 * t

10.Area = Pi*r 2
