Answer: 43feet
Step-by-step explanation:
Perimeter= 135 feet
Since perimeter= 2πr
135 = 2πr
Recall that π = 3.14
135 = 2 × 3.14 × r
135 = 6.28 × r
135 = 6.28r
r = 135/6.28
r = 21.5
d = 2r
d = 2 × 21.5
d = 43 feet
Answer: 62.8in
Step-by-step explanation:
The formula for circumference is C=2πr. Put the values of 10 in for r and 3.14 in for pi, and you get an equation that looks like C=2(3.14)(10). Solving this equation gets you 62.8.

Answer:
that is the equation of the line, its slope is 1 and the y-intercept is 1 y = x + 1
Step-by-step explanation:
we can calculate the slope of this line passing through (4,5) and (8,9) like this:
m = (y2 - y1)/(x2 - x1)
m = (9 - 5)/(8 - 4)
m = 4/4
m = 1
so the slope is 1, and now we can use the equation of one point and the slope to write the line's equation:
y - y1 = m(x - x1)
y - 5 = 1*(x - 4)
y - 5 = x - 4
y = x + 1
that is the equation of the line, its slope is 1 and the y-intercept is 1
The answer of this question is gonna be A
