Recall:
Given:
length of arc = 10 feet
First, find the radius using the length of arc formula.
radius = 19.2 ft
Find the area of the sector:
Area of sector =

Answer:
Step-by-step explanation:
step 1
Find the radius of the circle
we know that
A circumference of the circle subtends a central angle of 360 degrees
so
using proportion
step 2
Find the area of sector
we know that
The area of the circle subtends a central angle of 360 degrees
so using proportion
Let
x ----> the area of the sector
28 is increased to 96.
72 is decreased to 45.
55 is increased to 90.
230 is increased to 250.
180 is decreased to 140.
Each segment on the grid represents 1 unit.
Answer:
The triangle is shown in the below diagram.
Step-by-step explanation:
It is given that each segment on the grid represents 1 unit and point A is a vertex of a right angle triangle.
The height of triangle is 4 units, and the base is 5 units.
Let the coordinates of A be (x,y).
There are many possibilities to draw a right angled triangle having height 4, base 5 and vertex at A.
The height of the triangle is 4 units, so the coordinate of another vertex B is (x,y+4).
The base of the triangle is 5 units, so the coordinate of another vertex C is (x+5,y).
The triangle is shown in the below diagram.
