<h3>Answer:</h3>

The Area of the tray ≈380 cm

<h3>Solution:</h3>

We are given the diameter of the tray, which is equivalent to 22 cm.
We are asked to find the area of the tray.
Remember the formula:
Area of a circle = πr²
Where
π -> pi (3.14...)
r -> radius
Notice that we aren't given the radius. We're given the diameter only.
No reason to panic. We can easily find the radius by dividing the diameter by 2.
The radius is equal to 11 cm.
Now, plug the values into the formula:
A=π(11)²
A=121π
A≈380 cm

Hope it helps.

A square has an area of 100 square meters what is the perimeter of the square

Vladimir [108]

The perimeter would be 40 square meters because the area of the square is side times side and the side equals ten so 10+10+10+10=40

A social media website had 100,000 followers its first year. The number of followers increased by 9% each year. Write an exponen

chubhunter [2.5K]

Answer:

an exponential growth function to represent this situation is:

$x\left(t\right)=100,000\times \left(1.09\right)^t\:$

Step-by-step explanation:

We know that the exponential growth function is of the form

$x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t$

where

x(t) represents the value at time t

x₀ represents the initial value at time t = 0. In other words, it is the initial value (the amount before measuring growth or decay)

r represents the growth factor when r > 0 and decay factor when r < 0

t represents the of time intervals that have passed

In our case,

Given that

A social media website had 100,000 followers its first year. Thus,

x₀ = 100,000

The number of followers increased by 9% each year. Thus,

r = 9% = 0.09

Thus, substituting r = 0.09 and x₀ = 100,000 in the growth function

$x\left(t\right)\:=\:x_0\:\times \:\left(1\:+\:r\right)^t$

$x\left(t\right)=100,000\times \left(1+0.09\right)^t\:$

$x\left(t\right)=100,000\times \left(1.09\right)^t\:$

Therefore, an exponential growth function to represent this situation is:

$x\left(t\right)=100,000\times \left(1.09\right)^t\:$

Divide rupee 560 between ramu and muni in the ratio of 3:2

exis [7]

Step-by-step explanation:

Let the divided amount between ramu and muni be 3x and 2x respectively.

Then

3x + 2x = 560

5x = 560

x = 560/ 5

x = 112

Amount received by Ramu

= 3 * 112 = 336

Amount received by muni

= 2 * 112 = 224

Hope it will help :)
