Answer: volume of the cube is (7 cm)^3= 343 cm^3
first we can find the slope between the two points by using the slope formula
m=(y₂-y₁)/(x₂-x₁)
m=(3-(-7))/(-3-2)
m=(3+7)/(-3-2)
m=10/-5
m= -2
now that we have the slope, we can set up our equation. slope-intercept form is:
y=mx+b
where m is the slope and b is the y-intercept.
since we have the slope, we can choose one of the points that we are given to plug in for x and y, and then solve for b
-7 = 2(-2) + b
-7 = -4 + b
-3 = b
now that we have all the values we need, we can put it into our slope-intercept formula.
y=mx+b
y=-2x+(-3)
y = -2x -3
hope this helps
Answer:
7
Step-by-step explanation:
Let r represent the radius of cylinder.
We have been given that the height of a right circular cylinder is 1.5 times the radius of the base. So the height of the cylinder would be
.
We will use lateral surface area of pyramid to solve our given problem.
, where,
LSA = Lateral surface area of pyramid,
r = Radius,
h = height.
Upon substituting our given values in above formula, we will get:
Now we will find the total surface area of cylinder.







Therefore, the ratio of total surface area to lateral surface area is
.
Square root 27 is 3squer root 3 so the answer is 2 square root three
