1.) Identify the solid formed by the given net.

Question

a. cylinder
b. triangular prism
c. square pyramid
d. rectangular prism

2.) Name the solid according to its description:
The figure has two bases that are parallel congruent circles.
a. cylinder
b. rectangular prism
c. sphere
d. cone

3.) Find the lateral area of a cone with a radius of 7 ft. and a slant height of 13 ft. us 3.14 for pi and round to the nearest tenth.
a. 439.6 ft²
b. 324.5 ft²
c. 571.5 ft²

4.) find the surface area of a square pyramid with a base length of 24 cm and a height of 16 cm.
a. 1056 cm²
b. 1536 cm²
c. 816 cm²
d. 1344 cm²

use the diagram of the cylinder to answer the question. Use 3.14 for pi and round to the nearest tenth.
(the cylinder radius is 8 in and the height is 8 in)

5.) Find the surface area for the cylinder.

a. 2009.6 in²
b. 401.9 in²
c. 803.8 in²
d. 602.9 in²

Answer 1

#1 no net
#2 clearly not B. How many bases to cones and spheres have?
#3 recall that lateral area = 2πrs
#4 the slant height is 20 (use Pythagorean Theorem)
Thus the area is the square base + 4 triangles of base24 and height20
#5 no diagram, but use 2πr(r+h)

Answer 2

someone answer pls
