Answer:

Step-by-step explanation:

surface area=top circle+bottom circle+straight face

top circle=bottom circle=pi(w-1)^2

straight face=length*height=circle circumference*height

=2pi(w-1)(w+3)

surface area=2pi(w-1)^2+2pi(w-1)(w+3)

=2pi(w-1)(w-1+w+3)

=2pi(w-1)(2w+2)

=4pi(w-1)(w+1)

Answer:

4π(w+1)(w-1)

Step-by-step explanation:

The total surface area of the cylinder

= 2 x area of base circle + area of vertical surface

= 2x pi x radius^2 + 2x pi x radius x height

= 2π(w-1)^2 + 2π(w-1)(w+3)

= 2π[w^2-2w+1 + w^2+2w-3]

= 2π(2w^2-2)

= 4π(w^2 - 1)

= 4π(w+1)(w-1)

The figure shows the location of three points around a lake. The length of the lake, BC, is also shown.
Anastaziya [24]
A right triangle ABC is formed when we join three points around a lake.
Length of the side AC = 6 miles.
Length of the side BC = 2 miles.
We have to find Length of side AB.
Using Pythagorean theorem for Right triangle ABC , Right angled at B
→AB² + BC²= AC²
→ AB² + 2²= 6²
→ AB² = 36 - 4
→ AB²= 32
→ AB = √ 32
→→AB = 5.66 (approx)
Option (B) AB = 5.66 is Right choice.

The sum of 1/6, 2/3, and 1/4 is
zimovet [89]
1/6+2/3+1/4 
First find the highest common multiple of the denominators=12
Then multiply each term by the quotient of 12/denominator
So...it becomes 2/12+8/12+3/12
Add all the numerators and keep the denominator constant
It becomes (2+8+3)/12=13/12
                                 =1 1/12

If we decrease a dimension on a figure, how is the figure’s area affected?
Softa [21]

Answer:

A) area decreases

Step-by-step explanation:

<em>Example:</em> we have a 2 by 3 rectangle with area of 2*3 = 6. If we cut the first dimension in half, then we have a 1 by 3 rectangle that has area 1*3 = 3. The area has decreased. To keep the area the same, we would have to increase the other dimension some specific amount.
