It will be (6,4) all u do is slip it over t he x-axis

Find Radius
----------------------------------------------------------------------------------------------
Radius = Diameter ÷ 2
Radius = 6 ÷ 2
Radius = 3 units
----------------------------------------------------------------------------------------------
Find Area
----------------------------------------------------------------------------------------------
Area = πr²
Area = π (3)²
Area = 28.27 units² (Nearest hundredth)
----------------------------------------------------------------------------------------------
Find Circumference
----------------------------------------------------------------------------------------------
Circumference = πD
Circumference = π(6)
Circumference = 18.85 units (Nearest hundredth)
----------------------------------------------------------------------------------------------
Answer: Area = 28.27 units² ; Circumference = 18.85 units

Answer:
210 + 210 = b + t = 420
Step-by-step explanation:
Answer:
1. The tetrahedron has 4 vertices, 6 edges and 4 faces. Then V-E+F=4-6+4=2
2. The cube has 8 vertices, 12 edges and 6 faces. Then V-E+F=8-12+6=2
3. The octahedron has 6 vertices, 12 edges and 8 faces. Then V-E+F=6-12+8=2
4. The icosahedron has 12 vertices, 30 edges and 20 faces. Then V-E+F=12-30+20=2
5. The dodecahedron has 20 vertices, 30 edges and 12 faces. Then V-E+F=20-30+12=2.
If the angles are vertical, they must be equal.
If the angles are supplementary, then they add up to 180 degrees.
If each angles is x (since they are equal)
then
2x=180, or
x=90 °
The angles are each 90 °
