A microscope dilates the image of an organism 4 times its original dimensions. If the radius of a circular organism seen by the microscope is 8 cm, find the radius of the actual organism. Question 17 options: A) 4 cm B) 8 cm C) 2 cm D) 32 cm

2cm

Step-by-step explanation:

From the question, we are informed that a microscope dilates the image of an organism 4 times its original dimensions and that the radius of a circular organism has seen by a microscope is 8 cm.

Since the microscope makes the objects 4 times bigger, then the original radius will be:

= 8cm/4

= 2cm

The radius of the actual organism is 2cm.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
