Answer:
-0.4 or -10.4
Step-by-step explanation:
<h2><u>Given</u> :</h2>
The given equations are :
Let's solve for g in equation (2) :
now, let's plug value of g from equation (3) into equation (1) :
plugging value of b in equation (3) :
since " g " represents ground seats, number of ground seats :
=》396
And " b " represents balcony seat, therefore it is equal to :
=》312
ok ... in this situation... we need to find the area of the rectangle first as it is equal to the area of square .
so .... area of rectangle = l×b= 16×4
= 64 ∴area of square = 64
area of square = s×s
∴to find one side of the square ... we need to find the root of 64 = 8
∴one side = 8
now : perimeter of square : 4 × sides = 4 × 8 = 32 ║
It is 9 inches because the formula for the area of a circle is πr2 where the r represents the radius of the circle
The pi can be canceled out =
πr2 and 81 π leaving with
R2 and 81
The r2 represents a square number. So square root 81 and you would result in 9 as your answer
