Lesson 10: Volumes of Familiar Solids—Cones and Cylinders

1) 36\pie Phi is constant (pie)

2) the ball has greater value

Step-by-step explanation:

1) d=6 so r=d/2=3

V=4\pie *r^3/3= 4*3^3\phi/3=36\pie

2) for the first figure:

V= 4*4^3\pie/3= 256\pie /3

V2=BH/3=r^2\pie*H/3=3^2*6,5\pie/3=58,5\pie/3

256/3 > 58,5/3

So the ball has greater volume

the answer is 375 miles

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
