The formula for the area of a circle is pi*r^2. 3.14*16^2 = 803.84 centimeters squared
Answer:
m<W: 23
Step-by-step explanation:
8x - 9 + 30x - 4 + 13x - 11 = 180
51x - 24 = 180
51x = 204
x = 4
m<W:
8x - 9
8(4) - 9
32 - 9
23
Answer:
x = 90
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are in proportion, that is
=
, substitute values
=
( cross- multiply )
3x = 270 ( divide both sides by 3 )
x = 90
