Need to find:
- Perimeter of new square formed?

Solution:
- Side of smaller square = 3cm.
- Side of Bigger square = 9cm

Using formula:
- Perimeter of square = 4 × side

<u>Perimeter of smaller </u><u>square:</u>
⟹ 4 × 3
⟹ 12 cm

<u>Perimeter of Bigger square:</u>
⟹ 4 × 9
⟹ 36cm

Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square
⟹ 36 - 12
⟹ 24 cm

∴ Perimeter of new square formed is 24 cm.
Answer:
Step-by-step explanation:
The manager visits a park and interviews people who are waiting to use the tennis courts.
So First of all we need to know how to find the area of a circle.
Assuming that the apple pie is the shape of a circle
The formula for area is

Well we know that the radius = 3.14
And we know that
= 3.14 as well.
All we have to do is multiply..
3.14 x
= 30.95
So the area of the pie is 30.95 in
Good Luck! :)
Here, Function: h(t)= -16t² + 70t + 40
So, put the value of t, (time at which you want to calculate the height)
h(1) = -16(1)² + 70(1) + 40
h(1) = -16 + 110
h(1) = 94
Now, h(2) = -16(2)² + 70(2) + 40
h(2) = -64 + 180
h(2) = 116
h(3) = -16(3)² + 70(3) + 40
h(3) = -144 + 250
h(3) = 106
In short, Your height depends on time, and at each time it would be different, can be expressed by the coordinates on a Graph: (1, 94) (2, 116) (3, 106)
Hope this helps!
