Answer:
3
Step-by-step explanation:
36-27 = 9
Answer:
33.3 cm²
Step-by-step explanation:
Recall: Area Scale Factor = (Linear Scale Factor)²
Area scale factor = surface area of bigger cone/surface area of smaller cone
Let the surface area of the smaller cone be represented as x
Therefore,
Area scale factor = 75/x
Linear scale factor = radius of bigger cone/radius of smaller cone = 3/2
Thus:
75/x = (3/2)²
75/x = 9/4
Cross multiply
x*9 = 75*4
9x = 300
Divide both sides by 9
x = 300/9
x = 33.3 cm² (nearest tenth)
Answer:
well we can see the sign's a trapezoid
area of trapezoid = 1/ 2 × sum of parallel sides × height
= 1/ 2 × (7+5) × 4
= 1/ 2 × 12 × 4
= 24 Sq feet
