The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
Answer:
13
Step-by-step explanation:
500(x-3)=5000
500x-1500=5000
500x=5000+1500
500x=6500 /:500
x=13
Answer: use the website desmos and plug in the cordinate it gives u the line automaticaly.
Step-by-step explanation:
7200
You have to multiply 20×60 to get 1200 which is the area of one pennant multiply that by six and you get 7200 which is the area of six pennant
