Length of an arc is a "part" of the circumference of a circle.
The circumference is the perimeter of the circle. Formula is:
Where
C is circumference
d is diameter
Given diameter is 16, the circumference would be:
Now, the arc is 25 degrees, which is 25/360 th of the circle's circumference [recall, there is 360 degrees in whole circle].
So, we multiply the circumference we got by (25/360) to get our answer:
Minor Arc JH = 3.5 cm

Demi os working on a representation about a famous mathematician for her math class. She decides to make her poster in the shape of a plus sign. What is the total area of Demi's poster? The image and the measurements of the poster are in the attachment.
Answer: Total area = 1360 square inches
Step-by-step explanation: From the attachment, the poster is formed by two rectangles one over the other and a central part, which is a square. So, the total area is the area of the 2 rectangles minus the area of the square
A = Ar - As
As these forms are regular, the area of both is A = width * length
Area of the 2 rectangle:
width = 20 in
length = 12+20+12 = 44 in
There are 2, then:
Ar = 2.20.44
Ar = 1760
Area of the square:
width = length = 20
As = 20²
As = 400
Total Area:
At = Ar - As
At = 1760 - 400
At = 1360
The total area of the poster is <em><u>1360 square inches</u></em>.
