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

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

8. A triangle has sides with lengths of 6, 8, and 10 units, and a square has a

svet-max [94.6K]

Difference between the area of the triangle and square is 25

Step-by-step explanation:

Step 1: Find the area of the triangle given its 3 sides using the Heron's formula.

Area of the triangle = $\sqrt{s (s-a)(s-b)(s-c)}$ where s = $\frac{a + b + c}{2}$

⇒ s = (6 + 8 + 10)/2 = 24/2 = 12

$\sqrt{s(s-a)(s-b)(s-c)}$ = $\sqrt{12(12-6)(12-8)(12-10)}$

= $\sqrt{12(6)(4)(2)}$ = $\sqrt{576}$ = 24 sq. units

Step 2: Find the area of the square with perimeter = 28 units.

Perimeter of the square = 4 × side = 28

⇒ Side of the square = 28/4 = 7 units

⇒ Area of the square = (side)² = 7² = 49 sq. units

Step 3: Find the difference between the area of the square and triangle.

Difference = 49 - 24 = 25

What is the gradient between (0,3) and (1,8).

trasher [3.6K]

Step-by-step explanation:

Given

(x1 , y1) = ( 0 , 3)

(x2 , y2) = ( 1 , 8)

Now

Gradient =

$\frac{y2 - y1}{x2 - x1}$

$= \frac{8 - 3}{1 - 0} \\ = \frac{5}{1} \\ = 5$

Hope it will help :)
