What is the distance between point (-5,-6) and (-3,-8)
2 answers:
Answer:
Step-by-step explanation:
First, find the distance between the x values. From -5 to -3, the distance is 2 units. Then find the distance between the y values. From -6 to -8 the distance is 2. Then, use the Pythagorean Theorem to find the distance.
(a^2)+(b^2)=c^2 Where a and b are the distances between the x and y values.
C will be your answer.
(2^2)+(2^2)=c^2.
4+4=c^2
8=c^2
So the answer is the square root of 8.

Answer:
Area of the circle = π m² or 132.25 π m²
Step-by-step explanation:
To find the area, we will follow the steps below.
First write down the formular for the circumference of a circle, then use the formula to find the radius of the circle after which you can now find the area of the circle.
That is;
C = 2πr
where c is the circumference of the circle and r is the radius of the circle
From the question given, circumference C = 23π
23π = 2π r
Divide both-side of the equation by 2π
23π/2π = 2πr/2π
23/2 = r
radius = m
Formula for calculating the area of a circle is given by;
A = πr²
where A= area of the circle and r is the radius of the circle
A = π ( )²
A = π m² or 132.25 π m²
Area of the circle = π m² or 132.25 π m²
