Answer:
Step-by-step explanation:
circumference of cylinder = πd = 5π in
lateral area of cylinder = 5π×9 = 45π in²
Each colored face has a matching face on the other side of the figure.
green areas = 2(17×15) = 510 in²
blue areas = 2(12×17) = 408 in²
gray areas = 2(5×6) = 60 in²
yellow areas = 2(5×12) = 120 in²
red areas = 2(12×15) = 360 in²
total surface area = 45π + 510 + 408 + 60 + 120 + 360 ≅ 1,599.37 in²
When working with percents change them to decimals so 70% is .70 because a percent is just the number over 100. If you try it yourself do 70 divided by 100 and see what you get. For this problem you then multiply that by sixty as the total number of people included, which gets you 42 votes.
Answer:
The length is 600 ft
Step-by-step explanation:
We can solve this by applying the Pythagorean theorem
a^2 + b^2 = c^2
The hypotenuse (diagonal path) is 750
750 represents c, 750^2 is 562500
We also know the width (one side of the triangle)
450 can represent a, 450^2 is 202500
202500 + b^2= 562500
We can subtract 202500 on both sides to isolate the b^2
b^2= 360000
Square root both sides of the equation
B= 600
The length is 600 ft
Answer:
The scale factor is 2.
Step-by-step explanation:
Take the vertical sides of the 2 triangles.
Their length is 3 and 6 so the scale factor is 6/3 = 2.
Also we see than the horizontal lines are in the same ratio 4 : 2 = 2:1.
