$\huge\boxed{113.04}$

Diameter ( $d$ ) is equal to twice the radius ( $r$ ). So, find the radius by dividing $\frac{12}{2}$ . The radius, or $r$ , is $6$ .

Substitute in the value. $A=3.14*6^2$

Follow the order of operations and solve the exponent first. $A=3.14*36$

Multiply. $A=\boxed{113.04}$

Hey!

Let's write the problem.
$2x-4-5x=2$
Add like terms...
$-3x-4=2$
Add $4$ to both sides.
$-3x-4+4=2+4$
$-3x=6$
Divide both sides by $-3$ .
$\frac{-3x}{-3}=\frac{6}{-3}$

Our final answer would be,
$x=-2$

Thanks!

Area of semi circle: you know the radius is 5. 5^2 * pi = 25pi/2 = 12.5pi
For triangle: bh/2 = (10 * 10)/2 = 50
Add them together: 12.5pi + 50
12.5pi = 39.25
39.25 + 50 = 89.25
It’s closest to D

A gardener planted some seedlings at equal distances apart along a straight road. The 3rd seedling and the 5th seedling were 9/1

ratelena [41]

Answer:

Answer:

17 seedlings

Step-by-step explanation:

Given;

The seedlings are at an equal distance in a straight line.

Distance between 3rd seedling and 5th seedling = 9/10 m

So, distance between 3rd seedling and 4th seedling = 9/10 ÷ 2 = 9/20 m

So, the distance between two seedlings in a line = 9/20 m

The given distance between 2nd seedling and the last seedling = 6 3/4 m = 27/4 m
