Answer:
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Step-by-step explanation:
Each interior angle of a regular polygon is 4 times each exterior angle
∴sum of interior angles: (n-2)*180=4*360
n-2=8
n=10
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Answer:
2×10¹² cells → 90 g
mass of 1 red blood cell : 90÷(2×10¹²) = 45×10^-12 g = 4.5×10^-11 g
Answer: 1120.70
Step-by-step explanation:
The answer should be
<span>C = 28 π = 2π r
r = 14 m
A = π (14)² m ²
A = (22/7) (14) (14) m ²
A = 44 x 14 m ²
A = 616 m ²
