Circumference of a circle is 22cm find the area of its quadrant

Hey!

So the area of a quadrant in this circle would be 9.62cm^2

Step-by-step explanation:

To find the radius of the circle from the Circumference...

r=C /   2π *22 / 2π*

This gives us... 3.5 cm

We now use this to find the total area of the whole circle...

A = π x r^2 (radius squared)

This gives us 38.48 cm^2...

To find a quadrant we have to divide this answer by 4...

38.48 / 4...

GIVES US AN ANSWER OF 9.62cm^2!

HOPE THIS HELPS!!

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

7 is the median   7.875 is the mean
