The radius of a circle 6 cm what is the circles area?
dolphi86 [110]

Answer:

113.04 cm

Step-by-step explanation:

We know the formula to find the area of a circle is

A= pi(r^{2})

And we are told to use 3.14 instead of pi so what we have now is,

A=3.14(r^{2})

We are also told the radius, r, is 6. So our equation now looks like this,

A=3.14(6^{2})\\\\6^{2}is the same as 36, because 6x6 is 36.

Now we have,

A=3.14(36)  

Which equals 113.04 and that is the area!

Hope that helps and have a great day!

Hal earns n dollars per hour. Next month he
xenn [34]

Answer:

Total = 1.02n

Step-by-step explanation:

Given

Earnings = n

Raise = 2\% --- <em>not 296</em>

Total = n + 0.02n

Required

Simplify the expression for total earning

The total amount is derived from:

Total = Earnings + Raise * Earnings

Total = n + 2\% * n

Express percentage as decimal

Total = n + 0.02 * n

Now, we can solve further:

Total = n + 0.02n

Total = 1.02n

<em>Hence, the simplified expression is 1.02n</em>
