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.)

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
