15) The diameter of a cylinder is 12 and height is 11. Find the surface area of the figure. ​
kirza4 [7]

Answer:

A=640.88

Step-by-step explanation:

if the diameter is 12, the radius , r=12/2=6

we have r=6, h=11

Surface area, A= 2πrh+2π r^2

A=2*3.14*6*11+2*3.14*(6)^2=640.88

PLES HELP ME June knits scarves and hats for kids in her community. She has knitted six less than twice as many hats as scarves,
Thepotemich [5.8K]
Let x = hats she knitted

Less than means to subtract and it’s an order switcher so it would be

2x - 6 = 78

First step: Add six to both sides -6 + 6 = 0 6 + 78 = 84

2x - 6 = 78
+ 6. +6

2x = 84

Second step: Divide the coefficient on both sides, two is the coefficient

2x/2 = x
2/84 = 42

Therefore, the answer is x= 42

A company uses a combination of three components- A, B and C to create three different drone designs. The first design Glider us
FrozenT [24]

Answer:

Consider the following calculations

Step-by-step explanation:

Since 1 Blimp uses 2 components of B and C each

=> choosing 2 components of B(remaining after using in other prototypes) for 1st model= 22C2

choosing 2 components of B(remaining after using in other prototypes) for 2nd model= 21C2

choosing 2 components of B(remaining after using in other prototypes) for 3rd model= 20C2

choosing 2 components of B(remaining after using in other prototypes) for 4th model= 19C2

choosing 2 components of B(remaining after using in other prototypes) for 5th model= 18C2

and choosing 2 components of C(remaining after using in other prototypes) = 24C2

Similarly for C

P(5 prototypes of Blimp created)=[(22C2 / 25C2 )*(24C2 / 25C2 )] + [(21C2 / 25C2 )*(23C2 / 25C2 )]+[(20C2 / 25C2 )*(22C2 / 25C2 )]+[(19C2 / 25C2 )*(21C2 / 25C2 )]+[(18C2 / 25C2 )*(20C2 / 25C2 )]
