Answer:
Step-by-step explanation:
Area of a square platform = Length × Length
A = L² (note that all the sides of a square are equal)
Given
A = 16m²
L² = 16
L = √16
L = 4m
Hence the dimension of the square is 4m by 4m (use the dimension when sketching the diagram. Al the sides is the diagram must be the same i.e 4m)
Perimeter of the square = 4L
P = 4(4)
P = 16m
Hence the perimeter of the platform is 16m
Answer:

I think that is that answer
Answer:
Three and seventy-five hundredths
Step-by-step explanation:
1)
V=hpr^2
r=√(V/(hp)), using 216p for V and 3 ft for h you get:
r=√(216p/(3p))
r=√72
r≈8.5 ft (to nearest tenth of a foot)
2)
The volume of these ice cream cones is half the volume of a sphere plus the volume of a cone...
V=((4pr^3)/3)/2+(hpr^2)/3
V=(4pr^3)/6+(hpr^2)/3
V=(p/3)(2r^3+hr^2)
And the difference between them is:
V=(p/3)(2R^3+HR^2-2r^3-hr^2), given R,H,r,h=3,12,2,8:
V=(p/3)(2*27+12*9-2*8-8*4)
V=(p/3)(114)
V=38p cm^3
V≈119.38 cm^3 (to nearest one-hundredth of a cm^3)
3)
V=[(4pr^3)/3]/2
V=(2pr^3)/3 and when r=15yd
V=2250p yd^3
V≈7068.58 yd^3 (to nearest hundredth of a yd^3)
