The angle subtended by a section of a circle is 100". If the perimeter of the sector is 150cm
calculate the radius​

Radius of circle = 40 cm (Approx.)

Explanation:

Given:

Angle subtended by a section = 100°

Perimeter of the sector = 150cm

Find:

Radius of circle

Computation:

Perimeter of the sector = 2[Radius of circle] + Length or arc

150 = 2[r] + [θ/360][2πr]

150 = 2[r] + [100/360][2(3.14)r]

150 = 2[r] + [0.277][2(3.14)r]

150 = 2[r] + 1.74r

150 = 3.74r

r = 40 cm (Approx.)

Radius of circle = 40 cm (Approx.)

I would say that its they are descendant of a common ancestor. DNA shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago.
