subtract 13 from 30, and you get 17. Then you need to divide 17 and 30
674-392=282 so the answer would be 282 girls who participated
Area=πr^2 * β/360
=3.142*(6^2)(60/360)
18.852cm^2
option D is the answer
Answer:
The correct option is;
x = 1
Step-by-step explanation:
The parameters given are;
Location of circle center = 1 on the x axis
Radius of circle = 1
Required operation on circle = Revolving to create a sphere
To form a spherical shape by the rotation of a circular figure involves rotating the circular figure about a line passing through the center of the circle
Therefore, to form a sphere, the circle should be about a line that passes through x = 1
Hence, the circle should be rotated about the line x = 1.
Ramp² = 19² + 4²
ramp² = 361 + 16
ramp² = 377
