Answer:

2x2y+14xy−(−8x2y−9xy+5)

Step-by-step explanation:

Evaluation for x=1,y=1

2(1(2)(1))+(14)(1)(1)−(−8(1(2)(1))−(9)(1)(1)+5)

2(1(2)(1))+(14)(1)(1)−(−8(1(2)(1))−(9)(1)(1)+5)

=28

This is the best I can do when given the example of x = 1 and y = 1

Hope this helps you!!

A sphere is inscribed in a cube with a volume of 64 cubic inches. What is the volume of the sphere? Round your answer to the nea
erma4kov [3.2K]

Answer:

the volume of the sphere is

33.51 in^{3}

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, sphere and cube.

Given data

Volume of cube v =   64 cubic inches

since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,

we know that volume of cube is expressed as

v= l*b*h

v=l^{3}

64= l^{3}

l= \sqrt[3]{64}

l= 4 in

also diameter d=length l

Diameter d=  4in

Radius r =  \frac{d}{2}= \frac{4}{2}= {2 in}

Height h=4in

we know that the volume of a sphere is given by

v= \frac{4}{3} \pi r^{3}

substituting into the formula we have

v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}
