Answer:
1.54 in²
Step-by-step explanation:
Given that,
→ Radius (r) = 0.7 in
Formula we use,
→ πr²
The area of the circle will be,
→ πr²
→ (22/7) × 0.7 × 0.7
→ (22/7) × 0.49
→ [ 1.54 in² ]
Hence, area of circle is 1.54 in².
Hey there!
I'll assume we're using the slope-intercept form equation:
y = mx + b
m = slope
b = y-intercept
First, we keep the y, because it's value depends on the x value given.
Next, we find the slope. Slope is defined as rise/run, so we take two points on the graph, find how much taller one is from another, and how far right/left they are, put those values over each other, and we have out slope (m).
Finally, we need to determine the y-intercept, and that's as simple as seeing where the line crosses the y axis and writing down that value.
Hope this helps!
Answer:
r = 2x + 7
Step-by-step explanation:
get r on one side
8x + 12 + 16 = 4r
divide both sides by 4 to get r by itself
8x/4 + 12/4 + 16/4 = 4r/4
2x + 3 + 4 = r
2x + 7 = r
or
r = 2x + 7
