Volumes are in ratio 27 : 1331
so ratio od individual lengths = cube roots = 3 : 11
and surface areas will be in the ratio 3^2 : 11^2 = 9:121
so surface area of the larger figure is 121 * 18 / 9 = 242 mm^2
Answer:
BM = 9.5
Step-by-step explanation:
4.4x2.5=11
so
3.8x2.5=9.5
Since the triangle is equilateral, all its angles are equal to 60°
AO is the bisector⇒∠OAD = 30°
AO AO is the hypotenuse, ∠OAD = 30°⇒
OD=10:2=5ft
By the Pythagorean theorem




Answer: A)
ft²
