Answer:
a = 3
Step-by-step explanation:
Calculate the distance d using the distance formula and equate to 4
d = 
with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (2, a)
d =
=
=
= a + 1 then
a + 1 = 4 ( subtract 1 from both sides )
a = 3
Answer:
S = 15π = 47.12
length of arc S = 15π
Attached is the image of the arc.
Step-by-step explanation:
Given;
Radius arc r = 10
Angle at the center of arc ⍉ = 3π/2
The length of the arc S can be derived using the formula;
S = r × ⍉
Substituting the values;
S = 10 × 3π/2
S = 30π/2
S = 15π = 47.12
length of arc S = 15π
Rise over run = y2 - y1 / x2 - x1
3-12/-8 - (-17)
-9/ 9 which simplifies to —> -1 = slope
Answer:
Option C. 144 square inches is the correct answer.
Step-by-step explanation:
We have been given a square with one side with a measurement of 1 foot and we have to calculate the area in square inches.
First we know that 1 foot of length = 12 inches on scale
Therefore side of the square is 12 inches
Now the area of the square will be = (Side×Side) = (Side)²
= (12)² = 144 square inches.
So the area of the square will be 144 square inches.
