Find the surface area of this cylinder using pie.
Answer:
Thus, the surface area of a cylinder involving pie is:
[tex]\:\:\:A=36\pi \:[/tex] in²
or
[tex]A\approx 113.1[/tex] in²
Step-by-step explanation:
Given
radius = r = 2 in height = h = 7 inUsing the formula to determine the surface area of a cylinder:
[tex]A=2\pi \:rh+2\pi \:r^2[/tex]
[tex]A=\left(2\times \pi \times \:2\times 7\right)+\left(2\times \pi \times \:2^2\right)\:[/tex]
[tex]\:\:\:A=36\pi \:[/tex] in²
Thus, the surface area of a cylinder involving pie is:
[tex]\:\:\:A=36\pi \:[/tex] in²
or
[tex]A\approx 113.1[/tex] in²

1. 3 cans of pudding costs $2.48 at Store A and 6 cans of the same pudding costs $4.50 at Store B. Which store has the better buy on these cans of pudding?
Answer:a
Step-by-step explanation:
Answer:
Store B because if you take 2.48 divided by 3 to figure out the cost per can aka one can it will be 0.826 repeating and that's for store A . While store B you take 4.5 divided by 6 to and get 0.75 per can so Store B is the best option since 0.75 is smaller than 0.826.

Sara is ordering a circular rug for her living room. The area of the rug is 157 feet squared. What is the radius of the rug to the nearest tenth of a foot?
Answer:
157/ pi= 49.97 which is r squared, so the square root of 49.97= 7.06 or 7.1
so the radius of the rug is 7.1 ft

How
many cubic metres of earth must be dug to construct a well 7
m deep and of diameter 2.8 m?
Answer:
43.103m³
Step-by-step explanation:
This is just finding the volume of a cylinder problem.
Area of a circle = πr²
Area of circle * length of cylinder = volume
3.14*(1.4)² = 6.158m²
6.158*7 = 43.103m³

Solves a systems of linear equations in two variables.
Solve the following systems by graphing
1) 2x + y = 5 and x-3y = - 8
2) 6x - 3y = - 9 and 2x + 2y = -6
Solve the following systems by substitution
3) y = 5x-3 and -x - 5y = - 11
4) 2x - 6 = 24 and x - 5y - 22
Solve the following systems by elimination
5) - 4x - 2y = -2 and 4x + 8y = -24
6) x - y = 11 and 2x + y = 19
write an equation in slope-intercept form of the line that passes through the given points (-4,-2) (8,-2)
Answer:
y=-2
Step-by-step explanation:
First, find the slope using the slope formula: m=y2-y1/x2-x1
Plug the numbers into the equation and get 0
Using the slope and one of the coordinates, put the equation into point-slope form: y-y1=m(x-x2)
y+2=0(x+4)
Distribute and simplify to get the final answer.
y+2=0+0
y=-2
