PLEASEEE HELP ME FIND THE SURFACE AREAWill Mark Brainliest!!

Answer 1

Answer:

100.48

Step-by-step explanation:

Surface area of a cylinder = [tex]2\pi r^2+2\pi rh[/tex]

Where r = radius and h = height

We are given the diameter ( 4 cm ) and the height ( 6cm )

To convert diameter to radius we simply divide by 2 ( because radius = half the length of the diameter )

4 / 2 = 2 Thus, r = 2

Now we plug in the values of the radius and height into the surface area of a cylinder formula ( note we must use 3.14 for π as the question says to. not doing so can result in a wrong answer )

[tex]SA=2(3.14)(2^2)+2(3.14)(2)(6)\\2^2=4\\4*3.14=12.56\\12.56*2=25.12\\\\2*3.14=6.28\\6.28*2=12.56\\12.56*6=75.36\\\\75.36+25.12=100.48\\SA=100.48cm^2[/tex]

Use the Imaginary number exponents rules

[tex] {i}^{2} = - 1[/tex]

[tex] {i}^{3} = - i[/tex]

Hello :) ok so to find AC you would have to use sin. It would be sin70= x/4. To find AC you would have to multiply 4 by sin70 which is 3.758 or to the nearest hundredth would be 3.76. I hope I helped, if you need a more in depth explanation lmk

x^2-3=0 solve for all real values of x

Answers

Step-by-step explanation:

x²-3=0

x²=3

x=√3

stay safe healthy and happy.

Answer:

x = √3

x = - √3

Step-by-step explanation:

x^2 - 3 = 0          Add 3 to both sides

x^2 = 3               Take the square root of both sides.

sqrt(x^2) = sqrt(3)

x = +/- sqrt(3)

Remember that the - root is also a solution to the question. Also for this question don't put the - sign under the root sign. That is an entirely different question.

If one leg of a right triangle is 4/7 and the hypotenuse is 10/6, then the other leg is​

Answers

A right triangle has two legs and a hypotenuse
a = shorter leg
b = longer leg
c = hypotenuse
We know b-a=4, or b = a+4

The Pythagorean theorem states:
a2 + b2 = c2

a2 + (a+4)2 = c2
a2 + (a+4)2 = 80
a2 + a2 + 8a + 16 = 80

Combine terms
2a2 + 8a - 64 = 0

Divide by 2
a2 + 4a - 32 = 0

Factor
(a+8)(a-4) = 0
a = 4, -8

We throw out the -8 solution because we can't have a negative measure.

So a = 4
b = 8
c = √80 = 4√5

The legs are 4 and 8.

Answer:

44m²

Step-by-step explanation:

GIVEN :-

Lengths of all the sides of the figure.

TO FIND :-

Area of the figure

SOLUTION :-

Divide the whole figure into 2 rectangles.

Dimension of 1st rectangle = 6m × 2mDimension of 2nd rectangle = 8m × 4m

Area of 1st rectangle = 6 × 2 = 12m²

Area of 2nd rectangle = 8 × 4 = 32m²

∴ Area of the whole figure = 32 + 12 = 44m²

a) what is his total expenditure?
b) how much does he save in a month?​

Answers

Step-by-step explanation:

Total money=15000

food=20%

edu.=10%

food AMT=20% of 15000

=20/100*15000

= 3000

education AMT= 10/100*15000

=1500

savings = 15000-1500-3000

=Rs10500

total expenditure=1500+3000

If he needs $1,000 in total and already has $250, you can do 1,000 - 250 to get 750. A simpler way to.do that could be to take 1,000 - 200 to get 800, and then subtract another 50.

The answer is 750 dollars
