Answer:

14.32 inches to nearest thousandth.

Step-by-step explanation:

Circumference = π * d where d = the diameter.

So 45 = π * d

d = 45 / π

= 14.32 inches

Answer:

diameter ≈ 14.32 in ( 2 dec. places )

Step-by-step explanation:

the formula for calculating the circumference (C) of a circle is

C = πd ← d is the diameter

isolate d by dividing both sides by π

d = $\frac{C}{\pi }$ = $\frac{45}{\pi }$ ≈ 14.32

What is the measure of DEF? Pls help me asap

Yakvenalex [24]

Step-by-step explanation:

3y +4 =5y -10

2y = 14

y = 7

DEF = (3Y+4)× 2 OR (5Y-10) ×2 OR (5Y-10+ 3Y+4)

Def= (3 ×7+4)×2

Explain why a two-dimensional net is useful for finding the surface area of a three-dimensional figure. Answer as soon as possib

Allushta [10]

A two-dimensional net is useful because it flattens the 3-d figure so that you can see all the faces of the figure. You can calculate the area of each face to find the surface area.

Help me please not understand

Alborosie

Answer:

1st Option.

Step-by-step explanation:

f(0) = g(0) is correct because both f(0) = -2 and g(0) = -2; they both intersect at that point and therefore the y-value is the same.

The other answer choices don't work because the y-value outputs don't match each other.

28n^4 +16n^3 -80n^2

we can factor out a 4n^2

4n^2 (7n^2 +4n - 20)

4n^2 (7n-10) (n+2)
