Answer:
153.86 square feet
Step-by-step explanation:
The formula for the area of a circle is : ![\pi *radius^2](https://tex.z-dn.net/?f=%5Cpi%20%2Aradius%5E2)
To work this out you would simply multiply pi by the radius of 7 squared, this gives you 153.86. This is because if you were to substitute the values into the formula you would also get the same answer.
1) Multiply pi by 7 squared.
![\pi *7^2=153.86 feet^2](https://tex.z-dn.net/?f=%5Cpi%20%2A7%5E2%3D153.86%20feet%5E2)
In this question pi is as 3.14
Answer is x = (355*r^-35)/7 hope led me know if you have any questions
Answer:
Kalpana = 49
Abhilasha = 77
Gouri = 16
Step-by-step explanation:
You can write this as an equation, where Kalpana is x, to make it easier to understand.
Gouri + 33 = x
Gouri = x - 33
Abhilasha - 28 = x
Abhilasha = x + 28
Now just plug in 49.
49 - 33 = 16
49 + 28 = 77
