Find the area of each circle to the nearest tenth, if necessary. Use 3.14 for π.

Solution:

Given that,

We have to find the area of circle

The area of circle is given as:

Where, "r" is the radius of circle

Figure 1

From figure,

Diameter = 14 m

Thus,

Thus area of circle is 153.9 square meter

Figure 2

Radius = 5 feet

Therefore,

Thus area of circle is 78.5 square meter

yo answer should be 6 if im not mistaken

step-by-step explanation:

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
