Hi I am putting the questions that don't have pictures with the problem from my Measurement Unit Test I need my answers checked because as of now I have a c in math and I want to raise it so I need to make sure my answers are correct!
1. Which solid has 2 bases that are triangles and 3 lateral surfaces that are rectangles?
A. Triangular Pyramid
B. Rectangular Prism
C. Triangular Prism***
D. Rectangular Pyramid
13. What is the surface area of a sphere with a radius of 5 meters rounded to the nearest square meter?
A. 250m^2
B. 314m^2*****
C. 340m^2
D. 523m^2
14. What is the volume of a sphere with a radius of 4 meters rounded to the nearest square meter?
A. 67m^3
B. 201m^3*****
C. 268m^3
D. 804m^3
17. What is the volume of a sphere with a radius of 3 centimeters rounded to the nearest cubic centimeter?
A. 113cm^3*****
B. 905cm^3
C. 85cm^3
D. 38cm^3
#14 wants volume, not area
the others look good.
Hmm. Some of your answers are questionable. In the diagram for the test concerning the skew lines, there is no option for {AE and GH}. Also, for No. 7, the correct answer is a triangular pyramid, most certainly not a cube. I haven’t completed the rest of the test just yet but perhaps you should check back to your answers that you posted here and see if maybe you took a similar but different test or had some typos?
1. To determine the answer to this question, you need to understand the properties and characteristics of different solids. The solid that has two bases that are triangles and three lateral surfaces that are rectangles is called a Triangular Prism. The correct answer is C. Triangular Prism.
13. To find the surface area of a sphere, you can use the formula: Surface Area = 4πr^2, where r is the radius of the sphere. In this case, the radius is 5 meters. Substitute this value into the formula, and calculate the result: Surface Area = 4 * 3.14 * 5^2 ≈ 314 square meters. The correct answer is B. 314m^2.
14. The volume of a sphere can be calculated using the formula: Volume = (4/3)πr^3, where r is the radius of the sphere. In this case, the radius is 4 meters. Substitute this value into the formula, and calculate the result: Volume = (4/3) * 3.14 * 4^3 ≈ 201 cubic meters. The correct answer is B. 201m^3.
17. Similar to the previous question, the volume of a sphere can be calculated using the formula: Volume = (4/3)πr^3, where r is the radius of the sphere. In this case, the radius is 3 centimeters. Substitute this value into the formula, and calculate the result: Volume = (4/3) * 3.14 * 3^3 ≈ 113 cubic centimeters. The correct answer is A. 113cm^3.
Please note that answers may vary slightly due to rounding, but the provided answers are the closest and most accurate choices. Good luck with your math grade improvement!
to anyone looking for help/answers, fret not for if you have searched this far these should be the correct answers.
