Answer:
D. 340 square inches
Step-by-step explanation:
Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.
10 x 10 = 100
The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2
So:
10 x 12 = 120/2=60
From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.
60
x 4
240 + 100 = 340 square inches
if this helped brainliest would be epic
The answer should be c :)
You have to move the decimal 2 places over so like if it’s 2.00 the percent would be 200%, and if it was .20 it would be 20%
The side length is the square root of 8. Because the square has 4 equal sides, the side lengths must be equal. So the answer is approximately 2.83.
The answer is:
20 m² .__________________________________________________________Explanation:__________________________________________________________
Formula for "S.A." (Surface area) of a cylinder
S.A.
= 2
r² + 2
* r * h ;
_______________________________________in which "r" = length of radius of circle at the end; and "h" = "height" ;
__________________________________________Given: r = 2 m ; and h = 3 m ;
__________________________________________ We can "plug in" these given values; and solve for the "surface area" in terms of
"
" .
____________________________________________S.A. = 2
r² + 2
* r * h ;
= 2
* (2)² + 2
* (2) * (3) ;
= 2
* (4) + 2
* (6) ;
= (8
) + (12)
= 20 m² ._______________________________________
