Answer:
√73 or 8.54 units to the nearest hundredth.
Step-by-step explanation:
Use the distance formula with points (8, 3) and (0, 0).
D = √ [(8 - 0)^2 + (3 - 0)^2]
= √(64 + 9)
= √73 units.
The reciprocal is the deominator. so the answer is 1
Answer:
SA = 105 in^2
Step-by-step explanation:
To find surface area, find the area of all the shapes and add it all together. This shape has 4 triangle faces. They are all the same. So we can find one of them and times by 4.
Area of a triangle:
A = 1/2b•h
= 1/2• 5 • 8
= 1/2 • 40
= 20
One triangle has area 20, so times by 4 (bc four triangles)
4•20
= 80
Area of square 5•5
= 25
Add the areas:
80 + 25
= 105 sq in
