The area is 3.14 for number 6
Ilia_Sergeevich [38]2 years ago
5 0

Answer:

Step-by-step explanation:

the top one... which is I am assuming asking for the diameter?

Formula = d=2r  

so 2x4 which is 8

But if you were wanting number 6

the formula is A=πr2

which would be 3.14 x 1^1 = 3.14

you take the diameter and square it and then multiply it by pi

What is the answer to this?
Keith_Richards [23]

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.  

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

z^{2}  = 28.31^{2}  - 25^{2}

z = 13.29

If the simple interest on ​$4000 for 8 years is ​$2240​, then what is the interest​ rate?
mixer [17]

~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$2240\\ P=\textit{original amount deposited}\dotfill & \$4000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &8 \end{cases} \\\\\\ 2240 = (4000)(\frac{r}{100})(8) \implies 2240=\cfrac{32000r}{100}\implies 2240=320r \\\\\\ \cfrac{2240}{320}=r\implies 7=r
