Answer:
Step-by-step explanation:
Just find the area for each individual shape, then add them all up.
3x8/2=12
3x8/2=12
7x3=21
3x8=24
We're actually missing a side value, and it's on the hypotenuse of the triangle shape, so we use this formula to find it.
8²+3²=c²
64+9=c
73=c
√73=8.5
8.5x7=59.5
Add them all up, and the final answer is...
128.5

Answer:
4. dy/dx = -2
8. dy/dx = 1/2 x^(-3/2)
10/ dy/dr = 4 pi r^2
Step-by-step explanation:
4. y = -2x+7
dy/dx = -2(1)
dy/dx = -2
8. y = 4 - x^-1/2
dy/dx = - (-1/2x^ (-1/2-1)
dy/dx = 1/2 x^(-3/2)
10. y = 4/3 pi r^3
dy/dr = 4/3 pi (3r^2)
dy/dr = 4 pi r^2
From diameter you get radius by halving the diamter
radius = 14/2 = 7 cm
volume, height, and radius of a cylinder are all related by formula for volume of cylinder:
V = <span>πr²h
If we want to solve for h, we divide both sides by </span><span>πr² and get
h = V/(</span><span>πr²)
since V = 112</span><span>π and r = 7, h is equal to
h = (112</span>π)/(<span>π*7²) = 112/49 = 16/7 cm
height is C 16/7 cm
