Answer:

Convex, cyclic, equilateral, isogonal, isotoxal. In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon interior angles is 3240 degrees.

Step-by-step explanation:

Sorry if that was more than 2 figures

Solve the inequality. 5 – 3a < –10

Murljashka [212]

Answer:

A=5

Step-by-step explanation:

5-3a<-10 is the same as

5-3a=-10

So to solve it just solve for a.

subtract 5 from both sides

-3a=-15

dived -3 from both sides to get a alone

A=5

At the park there is a pool shaped like a circle. A ring-shaped path goes around the pool. Its inner diameter is 22yd and its ou

First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.

The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:

22/2 = 11 yards
32/2 = 16 yards

Then solve for the area of both circles.
π $11^{2}$ $= 121$ π ≈ 380.13 (area of the pool)
π $16^{2}$ $= 256$ π ≈ 804.25 (area of the whole thing)

Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:
$804.25 - 380.13 = 424.12$ (area of the walkway)

Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:

424.12 ÷ 6 ≈ 70.69

So you'll need 71 gallons of paint!

Hope I helped and let me know if you have any questions :)
