Answer:
hi friends new friends
The diameter will be given by 50 cm ÷ 3.142 = 15.9134 cm
The radius will be 15.9134 ÷2 = 7.9567 cm or about 7.96 cm
The area of a circle is given by \pi × square of radius
Area = 3.142 × 7.96×7.96 = 199.0821 square cm
90° = complimentary
middle one = is neither
3rd one is supplementary
11,15,19,23,27,31,35,39,43,47,51,....
x^2+ 2x +-48
product: -48 sum: 2
8, -6
x^2 +8x - 6x - 48
=> x(x+8) -6(x+8)
=> (x+8)(x-6)
Hope it helps...........
