i have unit 6 lesson 9 geometry foundations b surface area and volume unit test
for questions 8 and 9:
8. what are the lateral area and surface area of the cone shown below? round the answers to the nearest tenth. the figure is not drawn to scale.
A. LA= 829.4 ft^2, SA= 1,209.5 ft^2
B. LA= 829.4 ft^2, SA= 3.041.1 ft^2
C. LA= 380.1 ft^2, SA= 1,209.5 ft^2
D. LA= 380.1 ft^2, SA= 3,041.1 ft^2
THE CONE DOES NOT SHOW SO I DONT KNOW THE MEASUREMENTS
9. what is the volume of the given prism? round the answer to the nearest tenth of a centimeter. the figure is not drawn to scale.
A. 295.5 cm^3
B. 451.7 cm^3
C. 493.0 cm^3
D. 617.1 cm^3
AGAIN THE PRISM DOESNT EVEN SHOW UP ON MY TEST DOES SOMEONE HAVE THE MEASUREMENTS OR THE ANSWERS??
i really don’t wanna get a low grade bc the test didn’t show up
Contact your teacher since there seems to be a major error in the test.
thanks mrs. sue
What in the world
I need these as well! Please help me
I understand your frustration. Unfortunately, as an AI bot, I don't have access to specific test questions or their answers. However, I can explain how you can find the solutions yourself.
For question 8, to find the lateral area and surface area of a cone, you need to know the measurements of the cone - specifically the height and the radius. If the figure is not drawn to scale and you don't have the measurements, it will be difficult to solve this question accurately. However, if you have learned the formula for the lateral area of a cone (LA = πrl) and the surface area of a cone (SA = πr(r + l)), you can plug in the given measurements and calculate the answers. Just make sure to round to the nearest tenth as stated in the question.
For question 9, again, you need the measurements of the prism to calculate its volume. Without the figure or the measurements, it's challenging to solve this question accurately. However, if you have learned the formula for the volume of a prism (V = Bh, where B represents the base area and h represents the height), you can calculate the volume by plugging in the given measurements. Remember to round to the nearest tenth as instructed.
I recommend reaching out to your teacher or classmates for assistance if you don't have the measurements for the figures. They will be able to provide you with the necessary information, clarification, or potential error in the test.
A. LA= 829.4 ft^2, SA= 1,209.5 ft^2
SA = LA + πr^2
πr^2 = SA-LA = 380.1 = 121π
so, r^2 = 121
r = 11
LA = πr(r+s), so
11π(11+s) = 264π
121 + 11s = 264
s = 13
sin r^2 + h^2 = s^2, h = 4√3
so, the cone has base radius 11 and height 4√3
Do the others the same way.
As for the prism, there is no way to determine its area without some indication of its sides or volume or diagonals or something!
