Answer:
Circumferences, radii, and areas are one of the concepts concerning length and area. Also, the volume of 3 dimensional objects such as cubes, cylinders, pyramids, and spheres can be computed using geometry. ... In real life, geometry has a lot of practical uses, from the most basic to the most advanced phenomena in life.
Step-by-step explanation:
Area of the circle is 78.5 sq. units.
<u>Step-by-step explanation:</u>
Circumference of the circle = 31.4 units
2 π r = 31.4 units
2 × 3.14 ×r = 31. 4 units
r = 31.4 / (2×3.14)
= 5 units.
Area of the circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.

Answer:
y = -5(x-1)
Step-by-step explanation:
A y-intercept of 1 means that the point (0,1) falls on the line.
Slope-intercept form is 
where m is the slope...
Therefore, the slope-intercept equation is y-1=-5(x-0) or y-1=-5x
