Answer:
8 meters
Step-by-step explanation:
The height of the object and its shadow length are presumed to be proportional.
object height/shadow length = S/7= 40/35
Multiplying by 7 gives ...
S = 7(40/35) = 8
The statue is 8 meters tall.
Answer:
Step-by-step explanation:
Total surface area of a cone is given by the expression,
SA = πrl + B
Here, r = Radius of the circular base
l = slant height
B = Surface area of the base
Surface area of the circular base = πr²
= π(5)²
= 25π cm²
Slant height 'AC' = 
= 
= 
= 13 cm
Substitute the values in the expression of surface area,
SA = π(5)(13) + 25π
= 65π + 25π
= 90π cm²
Therefore, SA = 90π cm² will be the answer.
Answer:
The solution is (3,2)
Step-by-step explanation:
x - y = 1 →equation 1
-x + 3y = 3 →equation 2
by elimination method,
x - y = 1
-x + 3y = 3
-----------------
0 + 2y = 4
2y = 4
y = 4/2
y = 2
substitute y=2 in equation 1
x - y = 1
x - 2 = 1
x = 1 + 2
x = 3
∴(3,2) is the solution
