Surface area of cone is a sum of surface of its base and surface of its mantle.

Surface of its base is a circle which surface we will calculate like this:
Sb = pi*r^2     where r is d/2
Sb = 201m^2

Surface of mantle we calculate by:
Sm = pi*l*r    where l is length of side of cone.

l = \sqrt{r^2 + H^2} = 25.3
Sm = 635.8m^2

Total suface is:
Sb + Sm = 836.8m^2

What is the equation of the line that passes through the points (-4,1) and (4-1)
Nitella [24]

Answer:

y=-1/4x

Step-by-step explanation:

METHOD 1: The basic slope-intercept equation is <em>y=ax+b</em>. To achieve the slope with two points, this is the equation:

m = \frac{y2-y1}{x2-x1}

All you have to do is insert points (-4, 1) and (4, -1) into their corresponding locations.

m = \frac{(-1)-1}{4-(-4)}

With this equation, you will be able to find the slope. Then you can simply graph it to connect the two dots.

METHOD 2: Simply connect the two dots with a straight line (use a ruler or something with a straight edge.) Then count how many spaces up/down and left/right. If the line goes from top to bottom from left to right, it is a negative slope (hence, the -1/4.)

WILL GIVE BRAINLIEST <br><br> 5 = h/3 - 17 <br> h = ?<br> (h/3 is a fraction)
Nat2105 [25]

Answer:

h = 66

Step-by-step explanation:

We are given the equation of one variable h and we have to solve the equation for h.

The equation is given by 5 = \frac{h}{3} - 17

⇒ 5 + 17 = \frac{h}{3} {Adding 17 to both sides}

⇒ 22 = \frac{h}{3}

⇒ h = 22 × 3 {Since we know that if \frac{a}{b} = c then we can write a = bc}

⇒ h = 66 (Answer)
