\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
