Answer:
Step-by-step explanation:
radius r = 5 cm
Height h = 5 cm
Volume of cylinder = πr²h
= π * 5 * 5 * 5
= 125π cm³
Answer:
The slope intercept form is y=-7x+59
Step-by-step explanation:
y-y=m(x-x1)
y-3=-7(x-8)
y-3=-7x+56
+3 +3
y=-7x+59
Let h = height of triangle
h^2 + 12^2 = 15^2
h^2 + 144 = 225
h^2 = 225 - 144
h^2 = 81
sqrt{h^2} = sqrt{81}
h = 9 cm
For part B, we need to find surface area because it represents the perimeter of this 3-D figure. The formula needed is SA = B + LA.
1. First find the lateral area.
LA = perimeter of triangle • height
LA = ph
p = 15 + 15 + 24
p = 30 + 24
p = 54 cm
LA = (54)(9)
LA = 486 cm^2
2. We now find the base of each triangle. This is found by finding the area of each triangle and multiplying by 2.
A = (1/2)bh
A = (1/2)(24)(9)
A = 108 cm^2
A = 2•108 cm^2
A = 216 cm^2 = our B in the surface area formula.
SA = B + LA
SA = 216 cm^2 + 486 cm^2
SA = 702 cm^2
The amount of cardboard needed is 702 cm^2.
Answer:
A. t=66d
B. 66=d•t
C. d=66/t
D. d= 66t****
Step-by-step explanation:
the 66 ft/s is the speed, or the velocity.
since distance = time x velocity , or distance = time x rate
d = 66t
