The first step is to find the relationship between the square base and the surface area.
Surface area (SA) = area of the square (SS) + area of triangles.4(AT)
Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)
4(AT) = 864 - 324 = 540
Each triangle = 540/4 = 135 square in.
An area of one triangle (AT)= (base* slant height)/2
The base = 18 in.
<span>slant height = 2(AT)/base = 2(135)/18 = 15</span>
Answer:
6(37.5) + 45 = $270
Step-by-step explanation:
Answer: 84
Step-by-step explanation:
21 is 1/4 of ? The ? Is 4x21
Therefore, 21x4=84
27 in3 is the answer. this is because all dimensions of a cube are the same and if it fits a sphere of diameter 3 than the dimensions are 3x3x3 therefore 3*3*3 is 27 in3
Answer:
A
Step-by-step explanation:
To simplify the expression you first would need to multiple each part of it by -2 in order to remove the parenthesis
