The area of a circle is 16π cm2. what is the circle's circumference?
2π cm
4π cm
8π cm 1
6π cm

Step-by-step explanation:

Area of circle is given by :-

, where r is the radius.

Given : The area of a circle is

Then, we have

Since r cannot be negative , so r=4 cm

The circumference of a circle is given by :-

Hence, the circle's circumference = cm

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
