Answer:
The circumference of the circle is 28.26 m.
The area of the circle is 63.585
.
Step-by-step explanation:
To solve for the circumference of the circle, start by using the circumference formula of a circle, which is
. However, 3.14 will be used instead of
for this formula.
First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.
Next, plug in the radius into the formula, and the formula will look like
. Then, solve the equation, and the answer will be 28.26 m.
To solve for the area of the circle, start by using the area formula of a circle, which is
. However, 3.14 will be used instead of
for this formula.
For the area, plug the radius into the formula, and the formula will look like
. Then, solve the equation, and the answer will be 63.585
.
<wxz + <zxy= <wxy
<wxy= 105
105/2= 52.5
52.5 + 52.5 = 105
105 = 105
m<wxz = 52.5
Answer:
9.425
Step-by-step explanation:
first find the total length of a circle with the radius being 2cm
which u will obtain 12.566
not forget that in circle 90 degrees =1/4
so u will find 1/4 of 12.566 which= 3.141
then subtract 3.141 from 12.566
=9.425
