Answer:
Option A
Step-by-step explanation:
According to the distance formula , for any 2 points P & Q whose coordinates are (x¹ , y¹) and (x² , y²) respectively. So ,
NOTE = HERE x² , y² DOESN'T MEAN THE SQUARES OF x & y . THEY ARE JUST COORDINATES.
According to the question ,
Coordinate of C = (2 , -1)
Coordinate of D = (5 , 3)
Using distance formula ,
Answer:
Step-by-step explanation:
a hemisphere is half a sphere.
And if the formula for the volume of a sphere is:
we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere.
Since the radius is:
substituting this into the formula for volume:
this is the volume of the total sphere, thus the volume of a hemisphere is:
rounding to the nearest tenth:
