A boundary stripe 6 in. wide is painted around a rectangle whose dimensions are 120 ft by 230 ft. Use differentials to approxima

Nimfa-mama [501]

Answer:

350 square feet

Step-by-step explanation:

We are given that

Width of strip=6 in

Dimension of rectangle= $20 ft\times 230 ft$

We know that

Area of rectangle ,A=xy

Differentiate

$dA=\frac{\partial A}{\partial x}x+\frac{\partial A}{\partial y}y$

We have $\frac{\partial A}{\partial x}=y=230 ft$

$\frac{\partial A}{\partial y}=x=120$

$dx=\frac{12}{12}=1 ft$

1 ft=12 in

Because 6 in added in both side of breadth

dy= $\frac{12}{12}=1 ft$

Because 6 in added on both sides of length of rectangle

Substitute the values

$dA=230\times 1+120\times 1=350 ft^2$

Hence, the number of square feet of paint in the strip=350 square feet

You and your friends have decided to camp for a night. Your friend claims the area of his tent is 408 m2. Work out the area of h

slamgirl [31]

We know that
area of the tent=length*breath
length=240 cm---convert to m---> 240/100----> 2.40 m
breath=170 cm----convert to m---> 170/100----> 1.70 m

find the area
area=2.40*1.70-----> area=4.08 m²

therefore

the answer is
the friend's statement is incorrect the area is 4.08 m²

The volume v of a sphere with radius r is given by formula v=4/3 . if radius of a spherical rubber ball is 1 1\4 inches , what i

Aliun [14]

Actually, the correct volume formula is:
Sphere Volume = 4/3 • π • r³
Sphere Volume = (4/3) * PI * (1.25)^3
Sphere Volume = (4/3) * PI * 1.953125 
Sphere Volume = 8.1812308687 cubic inches
