Answer:

Step-by-step explanation:

1. Perimeter: 8cm + 8cm + 3cm + 3cm = 22cm

Area: 8cm x 3cm = 24cm

2. Perimeter: 5m + 5m + 5m + 5m = 20m

Area: 5m x 5m = 25m

3. Perimeter: 4m + 4m + 18m + 18m = 44m

Area: 4m x 18m = 72m

A circular sign is precisely designed to have an area of 50.24 square inches. What is the sign's circumference?

choli [55]

Step-by-step explanation:

First of all we need to know the formula for the circumference which is: $c=2\pi r$

We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.

The formula for the area is: $A=\pi r^2$ Solve for r;

$r^2=\frac{A}{\pi}\\ r=\sqrt[]{\frac{A}{\pi} }$

$r=\sqrt[]{\frac{50.24inch^2}{3.14} }$

$r=\sqrt[]{16inch^2}\\ r=4inch$

Now that we've found the radius, we simply plug it into the circumference formula.

$C=2\pi r\\C=2(3.14)(4)\\C=25.12inch$

-4(2x-3)>-28 please i need this result

Len [333]

-4 (2x - 3) > -28

Divide by -4 on both sides. Since we're dividing by a negative, we need to switch the sign.

2x - 3 < 7

Add 3 to both sides

2x < 10

Divide by 2 on both sides

x < 5
