The Y is the diameter Find Y Area of the circle ​

Mathematics
1 answer:
yarga [219]3 years ago
8 0

Answer:

<h2>Y = 22.56 cm </h2>

Step-by-step explanation:

To find the diameter Y of the circle we must first find the radius of the circle

Area of a circle = πr²

where

r is the radius

From the question

Area = 400cm²

Substitute the value into the above formula and solve for the radius

That's

400 = πr²

Divide both sides by π

We have

{r}^{2}  =  \frac{400}{\pi}

Find the square root of both sides

r =  \sqrt{  \frac{400}{\pi}  }

radius = 11.28 cm

Since we have the radius we can use it to find the diameter Y using the formula

diameter = radius × 2

radius = 11.28

Y = 11. 28 × 2

We have the final answer as

<h3>Y = 22.56 cm</h3>

Hope this helps you

A plane travels a distance of 22,000km in a time of 3.6 hours. What is its average speed rounded to the nearest whole number
fredd [130]

Answer:6111 km/hr

Step-by-step explanation:

Given

Distance travels by plane d=22,000 km

time taken t=3.6 hours

\text{distance}=\text{speed}\times\text{time}

average speed

v_{avg}=\dfrac{22,000}{3.6}=6111.11\approx 6111\ km/hr

Whats the answer????
Citrus2011 [14]

Step-by-step explanation:

the general slope intercept form is

y = ax + b

a is the slope (and always the factor of x). it is expressed as ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

b is the y-intercept, the y value of the point, where the line crosses the y-axis (in other words : the y value when x = 0).

so, look at the chart. where do we see points with integer coordinates (these are the easiest to read correctly and work with) ?

I see for example (0, -6) and (4, -7).

to go from the first to the second point :

x changes by +4 units (from 0 to 4).

y changes by -1 unit (from -6 to -7).

the slope a is therefore -1/4.

and the first point i picked gives us also automatically the y-intercept (-6).

so, the line equation is

y = (-1/4)x - 6

“Your salary is $25,000 and you will be receiving a 2.5% pay increase this year. What will your new salary be?”
Naddika [18.5K]
If your current salary is the 100%, and you get a 2.5% increase, that means the new salary would be 102.5% of 25,000. This percentage could also be written as 1.025, which you would multiply to 25,000 to get your new salary.

1.025 · 25,000 = 25,625

Therefore, your new salary would be $25,625
