Assuming 6 is the radius, we can use the formula to find the area of a whole circle, which is πr2

So it’s π6^2

Which is 113.1. BUT it’s a semi circle, so just divide by 2. So the answer should be 56.52 units squared.

in a triangle two sides of the same length the ratio of each of these sides to the third side is 5:3 if the perimeter of the tri

AveGali [126]

Answer:

Step-by-step explanation:

Perimeter of a triangle equals side 1 plus side 2 plus side 2

P = s1 + s2 + s3 side 1 = side 2 = x

x/side 3 = 5 / 3

x = (5/3) side 3

x (3/5) = side 3

perimeter = 65 slove for x

65 = x + x + 3x/5

325 = 5x + 5x + 3x

325 = 13X

25 = x equal side 1 and side 2

side 3 = 25(3/5) = 15

In a candy mix there are 4 green bars for every 3 red bars. How many red bars are there if there are 200 green bars

erastovalidia [21]

Answer:

Since there are 4 green bars for every 3 red bars and we are trying to find the number of red bars if there are 200 green bars, we can create the ratio:

4 x : 3 y

Where x is equal to the number of green bars and y is the number of red bars.

We know the number of green bars is equal to 200, so we can divide it by 4, giving us:

200 /4=50

Then we can solve for y , the number of red bars.

// Multiple y by 50

3 ⋅ 50 = 150

So for every 4 green bars, there are 3 red bars.

For every 200 green bars, there are 150 red bars
