Step-by-step explanation:
The radius r is the distance from the centre to a point on the circle.
Use the distance formula to calculate r
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (5, - 3)
r =

Answer:
30.9 cm²
Step-by-step explanation:
To find the surface area of this figure, we find the area of the base and the 3 identical sides.
The base is split into two identical right triangles. Let's find the area of one and multiply by two.
Half of 3: 1.5

There are two right triangles:

The area of one of the sides will be the same thing, except the height is 6.

There are 3 sides identical to this one:
.
Add 27 and 3.9:

Answer:
9.6 km
Step-by-step explanation:
Issa jogged 2/3 of the way home from school.
Then he was tired, so he walked the remaining 3200 m.
In other words, the remaining 3200 m is 1/3 of the way from school to home.
Let the distance from school to home be x. Therefore:

Therefore, from school to home he traveled 9600 m.
To put this is kilometres:
1000 m = 1 km
9600 m = 9600 / 1000 = 9.6 km
He traveled 9.6 km from school to home.
