The square root is
Just square the top and bottom of the fraction.
and
so we have 12/16 and then we reduce to 3/4
Formula is:
Number of reams per case x number of cases
11 x 12 = 132 reams
I hope this helps you
-( 3.5+1/3) ÷ 2.4+3/4
- 16/3 ÷ 11/4
-16/3 × 4/11
- 64 / 33
- 1 31 /33
The area of the shaded region = 330 sq cm
Step-by-step explanation:
Given,
The radius of small circle (r) = 4 cm
The radius of large circle (R) = 11 cm
To find the shaded region
Formula
The area of circle of radius r = π sq cm
So, The radius of the small circle = π× sq cm = 16π sq cm
The radius of the large circle = π× sq cm = 121π sq cm
Hence the area of the shaded region = 121π-16π sq cm
= 105π sq cm
= 105 × sq cm = 330 sq cm
