A hemisphere is half a sphere.
So, the volume of a hemisphere is the half of the volume of the complete sphere.
The formula for the volume of a sphere is:
V = (4/3) π (radius)^3
Using π = 3.14 and radius = diameter / 2 = 50 feet / 2 = 25 feet.
You get:
V = (4/3) (3.14) (25 feet)^3 = 65,416.7 feet^3
Answer: 65,416.7 cu. ft.
Answer:
6000 square millimeters
Step-by-step explanation:
Side length of the slanting side can be calculated using the Pythagorean theorem,
L = sqrt(30^2+40^2) = 50
sufrace area of a triangular prism
= surface area of the end sections + the surface area of the three side faces
= 2*(30*40/2) + 40*(30+40+50)
= 1200 + 4800
= 6000 mm^2
X% of y
x%=x/100
'of' means multiply
x% of y=x/100 times y so
48% of 8=48/100 times 8=384/100=3.84
3% of 119=3/100 times 119=357/100=3.57
26% of 280=26/100 times 280=7280/100=72.8
Answer:
y =5x
Step-by-step explanation:
k = y/x is the ratio for proportional relationships
k = 10/2
k = 5
Rewriting this equation
y= kx
y =5x
