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
Please get back to me
@Ms.Sue
#14,
V = (4/3)π(4^3)
= appr 268 m^3 , not m^2
the answer you gave would be the surface area. Is it a typo?
the others are correct
I'd be happy to help you check your answers! Let's go through each question one by one:
1. Which solid has 2 bases that are triangles and 3 lateral surfaces that are rectangles?
To answer this question, you need to identify the solid that has two triangle-shaped bases and three rectangular-shaped lateral surfaces.
A. Triangular Pyramid: This solid has one base that is a triangle and three lateral faces that are triangles. Therefore, it does not match the given description.
B. Rectangular Prism: This solid has two bases that are rectangles and four lateral faces that are also rectangles. It does not match the given description.
C. Triangular Prism: This solid has two bases that are triangles and three lateral faces that are rectangles. It matches the given description, so it appears to be the correct answer.
D. Rectangular Pyramid: This solid has one base that is a rectangle and four lateral faces that are triangles. It does not match the given description.
Based on this analysis, the correct answer for question 1 is C. Triangular Prism.
Moving on to the next question:
13. What is the surface area of a sphere with a radius of 5 meters rounded to the nearest square meter?
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.
Calculating using this formula, we have:
Surface Area = 4 * π * (5)^2
Surface Area = 4 * π * 25
Surface Area ≈ 314
Rounded to the nearest square meter, the correct answer for question 13 is B. 314m^2.
Moving on to the next question:
14. What is the volume of a sphere with a radius of 4 meters rounded to the nearest square meter?
To find the volume of a sphere, you can use the formula:
Volume = (4/3) * π * r^3
where "r" is the radius of the sphere.
Calculating using this formula, we have:
Volume = (4/3) * π * (4)^3
Volume = (4/3) * π * 64
Volume ≈ 268
Rounded to the nearest square meter, the correct answer for question 14 is C. 268m^3.
Lastly, let's move on to the final question:
17. What is the volume of a sphere with a radius of 3 centimeters rounded to the nearest cubic centimeter?
As we have already discussed earlier, the volume of a sphere can be calculated using the formula:
Volume = (4/3) * π * r^3
Calculating using this formula, we have:
Volume = (4/3) * π * (3)^3
Volume = (4/3) * π * 27
Volume ≈ 113
Rounded to the nearest cubic centimeter, the correct answer for question 17 is A. 113cm^3.
I hope this helps you in verifying your answers and improving your grade in math!+
