What is the radius of a circle with an area of 50.24 cubic inches? Use 3.14 for pi. Enter your answer in the box.
miss Akunina [59]

Answer:

r=4

Step-by-step explanation:

Area of a circle is

A = pi* r^2

We know the area and 3.14 = pi

50.24 = 3.14 * r^2

Divide each side by 3.14

50.24/3.14 =3.14 /3.14 *r^2

16 = r^2

Take the square root of each side

sqrt(16) = sqrt(r^2)

4 =r

The ratio of boys to girls in a class is 3:4. There are 35 students in the class. How many students are boys?
cricket20 [7]

Answer:

15 boys and 20 girls

Step-by-step explanation:

1. Since we cant simplify 3:4 we will leave it just like that.

2. 3x+4x=35

3. We add them both to give us 7x=35

4. We divide by 7 to get x by itself which results in 35/7=5.

x=5

5. Now we found x we can create 2 seperate soulutions:

3(5)=

and 4(5)=

Therefore there are 15 boys and 20 girls in the class. This makes sense because 15/20 reduced is 3 over 4.
