Step-by-step explanation:
always write what you know
circumference
U = 2 x pi x r
r = d/2
U = 39.25
rearrange and solve for r
U / (2 x pi) = r
solve for diameter
2r = d
(12,1):12³+1³=1728+1=1729
(10,9): 10³+9³=1000+729=1729

Well, it says to use a calculator to calculate them. So a calculator I would highly recommend is the Desmos graphing calculator.
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)
m =
=
= 
Use either of the 2 points for (a, b)
Using (a, b) = (- 4, - 1), then
y - (- 1) =
( x - (- 4)), that is
y + 1 =
(x + 4)
Answer:
$13
Step-by-step explanation:
928/116 = 8
8 + 5 = 13
