This quarter circle has a radius of 7 centimeters what is the area of this shape?

153.94

Step-by-step explanation:

I literally just typed in "how to find area of a circle with given radius" to refresh my memory lol. But then all I had to do was type in the radius and it gave me the 153.94

However, if you need the actual steps:

Use the formula: A = πr^2

A = π7^2

A = 49π

A = 153.938 which rounds to 153.94 :)

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
