The answer to your question is D
Answer:
The lateral surface area of the cone is
.
Step-by-step explanation:
We have.
Height of a cone is 60 m
Diameter of a cone is 10 m
Radius, r = 80 m
The lateral surface area of a cone is given by :
![A=\pi rl](https://tex.z-dn.net/?f=A%3D%5Cpi%20rl)
l is slant height of the cone,
![l=\sqrt{60^2+80^2} =100\ m](https://tex.z-dn.net/?f=l%3D%5Csqrt%7B60%5E2%2B80%5E2%7D%20%3D100%5C%20m)
Plugging all values in above formula,
![A=3.14\times 80\times 100\\\\A=25120\ m^2](https://tex.z-dn.net/?f=A%3D3.14%5Ctimes%2080%5Ctimes%20100%5C%5C%5C%5CA%3D25120%5C%20m%5E2)
So, the lateral surface area of the cone is
.
Answer:
slope = 5/6
Step-by-step explanation:
Since you were given two points, you can use the point-slope formula to find the slope. The general equation looks like this:
y₁ - y₂ = m(x₁ - x₂)
In this formula, "m" represents the slope. To find the slope, plug the values from the two points into the equation. Make sure to put the values from the same point in the variable with the same number.
Point 1: (-1, 8)
Point 2: (-7, 3)
y₁ - y₂ = m(x₁ - x₂) <----- Original formula
8 - y₂ = m(-1 - x₂) <----- Plug in "x" and "y" values from Point 1
8 - 3 = m(-1 - (-7)) <----- Plug in "x" and "y" values from Point 2
5 = m(-1 - (-7)) <----- Simplify left side
5 = m(6) <----- Simplify inside parentheses
5/6 = m <----- Divide both sides by 6
Answer:
12
Step-by-step explanation:
When the numerators are the same, the denominator that is bigger has a lesser value. In this case, the inequality > shows that
is bigger than the fraction next to it so in order to find a fraction that is lesser in value than
, we need to find a denominator that is <u>more than 10</u>, since 10 is the denominator of the first fraction. The only number more than 10 in the options is 12, so 12 is the answer.
