A flat three dimensional solid like a cube, a prism or a pyramid. When you cut out the "net", fold it and glue it together you can see what the three dimensional shape looks like. (It can be used in math)Draw a net of the polyhedron. Calculate the area of each face. Add up the area of all the faces.
Answer:
42 2/5 or 42.4
Step-by-step explanation:
Explanation:
Tommy calculated the area of the base by squaring the <em>diameter</em>, not the radius. If he's going to use the diameter in the area formula, he needs to divide the result by 4.
A = πr² = πd²/4
Pigs to horse
2 pigs to 3 horses
Pigs(n) to 24 horses
24/3= 8
2 x 8= 16
16 pigs to 24 horses
I hope this helped, have a nice day
Substitute y = 1/5 x + 1 into x + 5y = -15
x + 5y = -15
x + 5(1/5 x + 1) = -15
x + x + 5 = -15
2x = -20
x = -10
Plug in x = -10 into y = 1/5 x + 1
y = 1/5 (-10) + 1
y = -2 + 1
y = -1
(-10 , -1)
Answer is the last one
(-10 , -1)
