<u>Statement</u><u>:</u>
The circle has a diameter of 16 inches.
<u>To </u><u>find </u><u>out:</u>
The area of the circle.
<u>Solution</u><u>:</u>
- Diameter of the circle = 16 inches.
- Radius of the circle
- = Diameter ÷ 2
- = 16 inches ÷ 2
- = 8 inches
- We know, area of a circle = πr² where r is the radius.
- Therefore, the area of the circle
- = 3.14 × (8)² square inches
- = 3.14 × 64 square inches
- = 200.96 square inches
- = 201 square inches [rounded to the nearest square inch]
<u>Answer</u><u>:</u>
C) 201 square inches

Answer:
When rotating a point 180 degrees counterclockwise about the origin
(1,0)→(-1,0)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
When rotating a point 180 degrees counterclockwise about the origin
(x,y) →(-x,-y)
Given point ( x,y) = (1,0)
When rotating a point 180 degrees counterclockwise about the origin
(1,0)→ (-1,-0)
(1,0)→(-1,0)
