find the area of sector ghj given that θ=65°. use 3.14 for π and round to the nearest tenth. show your work and do not forget to include units in your final answer.

The area of a sector GHJ is

Step-by-step explanation:

step 1

we know that

The area of a circle is equal to

we have

substitute

step 2

Remember that the area of a complete circle subtends a central angle of 360 degrees

so

by proportion find the area of a sector by a central angle of 65 degrees

Use

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
