I need help!! This is a area question

A≈6503.88

Step-by-step explanation:

To find the area of a cirlce, you use the formula: A=(pi)r^2

You just plug in the radius (half of the diameter), punch it into the calculator and get your answer :)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
