Answer:

y=43 (alternate angle)

in triangle ADC

97+y+x=180(,sum of interior angle of triangle is 180)

x=180-97-43

Answer:

Step-by-step explanation:

z = 97° ( being opposite angles of parallelogram )

y = 43° ( being alternate angles )

In triangle ACD

y + x + 97° = 180° ( being sum of angles of triangle)

x + 43° + 97° = 180°

x = 180° - 140°

x = 40°

Andre45 [30]

Answer:

Step-by-step explanation:

Given

there are six integers to win a lottery

case-1 Integer not exceeding 40

no of ways to choose 6 incorrect numbers

$=\dfrac{^{34}C_{6}}{^{40}C_{6}}$

$=0.35$

Case-2 no of ways to choose 6 incorrect numbers out of 48 integers

$=\dfrac{^{42}C_{6}}{^{48}C_{6}}$

$=0.427$

Case-3 no of ways to choose 6 incorrect numbers out of 56 integers

$\dfrac{^{50}C_{6}}{^{56}C_{6}}$

$=0.489$

Cae-4 no of ways to choose 6 incorrect numbers out of 64 integers

$\dfrac{^{58}C_{6}}{^{64}C_{6}}$

$=0.54$

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

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

SOMEONE HELPPPPPPPPP!!!!!!

Finger [1]

Answer:

104 yd^2.

Step-by-step explanation:

Area of the 2 circles = 2 * π r^2

= 2 * π * 4^2

= 32 π yd^2.

Area of the side of the cylinder = 2 π r h

= 2 π * 4 * 9

= 72 π yd^2.

Total surface area = 32 + 72

= 104 yd^2.
