Answer:

a. 3.25 m

b.1.2 ft

Solution,

a. Let 'h' be the height of cylinder

Given,

Radius(r)=0.7 m

Volume(v)=5 m^3

Formula to find volume of cylinder

\pi {r}^{2} h

where r= radius and h= height

so,

\frac{22}{7}  \times 0.7 \times 0.7 \times h = 5 \\ or \: h =  \frac{5 \times 7}{22 \times 0.7 \times 0.7}  \\ or \: h =  \frac{35}{22  \times 0.49}  \\ or \: h =  \frac{35}{10.78}  \\ h = 3.25 \: m

b.

volume = 1.59 =  \frac{14}{12}  \times  \frac{14}{12}  \times h \\ 1.59 =  \frac{ {14}^{2} }{144}  \times h \\ h =  \frac{1.59 \times 144}{196}  \\ h = 1.168 \: ft \\ h = 1.2 \: ft

hope this helps...

Good luck on your assignment...

Answer: height = 1.16 ft

Step-by-step explanation:

14 inches = 1.17 feet

Height of the oven =

Height = volume / lw

H = 1.59 / 1.17*1.17

H = 1.16 feet

1/2 of 2/3 = 1/2 of ____ third(s) =____third(s)
adoni [48]
I'll write the equation again with the blanks filled in.

1/2 of 2/3 = 1/2 of two thirds = one third

2/3 is read as two thirds.

Half of 2/3 is 1/3, because 1/3+1/3=2/3

Hope this helps!

What are the coordinates of the terminal point determined t= 10pi/3?
erastovalidia [21]

we know that :

10*pi/3------> convert to degrees------> 10*180/3=600 degrees

600=360+240

240 degrees belong to the III quadrant  so

the x-coordinate is negative

the y-coordinate is negative  

240°=180°+60°

60 degrees is the angle to find the terminal point

let  ∅=60°

in the unit circle

r=1 units

x=-r*cos ∅----> x=-cos 60------> x=-(1/2)

y=-r*sin ∅----> y=-sin 60------> y=-(√3)/2

the point is ( -1/2 , -√3/2)
