Answer:
A = 178 cm^2
Step-by-step explanation:
Split the figure into a trapezoid and a rectangle
Area of trapezoid:
A = ((a+b)/2)*h
A = ((14+8)/2)*10
A = 150
Area of rectangle:
A = w*h
A = 2*14
A = 28
150+28
A = 178 cm^2
The lengths of the sides are 7, 23 and 24.
In order to find this, we need to add all of the side lengths together and set equa to 54. This will allow us to solve for n.
n + 3n + 2 + 4n - 4 = 52
8n - 2 = 52
8n = 54
n = 7
This gives us the length of the first side. To solve for the others, plug 7 into the equations.
3n + 2
3(7) + 2
21 + 2
23
Then the next one.
4n - 4
4(7) - 4
28 - 4
24
Answer:
Bella can complete work alone in 120 minutes
Step-by-step explanation:
Ana and Bella together can complete the shoveling in 30 minutes.
They can do a part of work in 1 minute =
Ana can do work alone in 40 minutes
She can do part of work in 1 minute =
So, Bella can do a part of work in 1 minute =
=
Bella can do part of work in 1 minute
Bella can do whole work in minutes = 120
Hence Bella can complete work alone in 120 minutes
The length of the radius will be 22 units.
<h3>What is the radius?</h3>
The radius of a circle is defined as the distance of the center of the circle to its outer layer. It is a locus of a point present at some distance from the center point.
Now from the question, we have an expression:
By solving the above equation we get
Hence the length of the radius will be 22 units.
