Answer:
Step-by-step explanation:
Represent the table with T, couch with C an umbrella with U
We have the following:
Required
Determine the cost of a table
Make T first equation
In the third equation, we have that:
By substituting 1275 for 2C + U
becomes
<em>Hence, a table costs $600</em>
Answer: 65.94 square meters
This value is approximate since pi = 3.14 is approximate
------------------------------------------------------------------
Work Shown:
Area of circle = pi*(radius)^2
A = pi*r^2
Area of smaller circle = pi*2^2 <<--- replace r with 2; which is the smaller radius
Area of smaller circle = 4*pi
Area of larger circle = pi*5^2 <<--- replace r with 5 (since 3+2 = 5); which is the larger radius
Area of larger circle = 25*pi
Area of shaded region = (area of larger circle)-(area of smaller circle)
Area of shaded region = 25*pi - 4*pi
Area of shaded region = 21*pi
Area of shaded region = 21*3.14 <<--- replace pi with 3.14 (approximate)
Area of shaded region = 65.94 square meters
105.6
Convert 40% to 0.4
Then multiply 0.4 by 264
0.4*264= 105.6
a is the best way to find it if there is points involved so keep that in mind
