What is the surface area of a sphere with a radius of 3 centimeters?

Answers

The equation for the surface area of a sphere is A=4 \pi r^(2)

So plug in 3 cm for radius "r"

A=4 \pi ( 3cm)^(2)

Simplify
A=4 \pi (9 cm^(2))
A=36 \pi  cm^(2)

Depending on your teacher, they might want you to leave it like this or plug in 3.14 for \pi
So your answer is either
A=36 \pi cm^(2)
or
A=113.04 cm^(2)

What is the result when 4x^2-17x+36 is subtracted from 2 x^2-5x+25?

Answers

2x^2-5x+25-(4x^2-17x+36)=\n 2x^2-5x+25-4x^2+17x-36=\n -2x^2+12x-11
2x^(2) - 5x + 25 - (4 x^(2) - 17x + 36) = 2x^(2) - 5x + 25 -4 x^(2) +17x -36 = (2-4) x^(2) + (-5+17)x + 25 - 36 = -2 x^(2) + 12x - 11

Find the value of g(5) if g(x)=x3−x.

Answers

Answer:

g(5) = 120

Step-by-step explanation:

to evaluate g(5) , substitute x = 5 into g(x)

g(x) = x³ - x , then

g(5) = 5³ - 5 = 125 - 5 = 120

What is slope point form

Answers

Answer: y-y intercept=slope(x-x intercept)

Step-by-step explanation: You calculate your slope and put that in for m. Then you find your x and y coordinates and plug those in. Then you have point slope form.

A monster truck tire will travel will travel 12.56 ft in one revolution. What is the radius of the tire?

Answers

If it travels 12.56 ft in one revolution, then the circumference of the tire is 12.56 ft.
Circumference = 2 x π x radius
12.56=2 x 3.14 x radius
radius x 6.28=12.56

Radius= 2 ft

Hope this helps :)
1 revolution
the part that touches the ground makes 1 full circle
therefor 12.56 is the cirvmerncere
circumfrence=2pir
12.56=circumfrence
12.56=2pir
divide both sides by 2
6.28=pir
aprox pi to 3.14 and divide both sides by 3.14
2=r

radius=2 feet
