Answer:
figure A the perimeter is 2(l+b)
2(3+12)=
2(15)=
30
figure B the perimeter is 2(l+b)
2(24+96)=
2(120)=
240
the scale of figure A to figure B is 30:240=
30/240=
1/8
It is barely less than 2 quarts, at 1.5 quarts.
D. 4.09*102 the answer is D
We would have two circles of 5cm diameter each, and a rectangle of the length pi*diameter and 2cm, so lets add them:
total = 2circles + rectangle
total = 2(2*pi*(5/2)^2) + pi*diameter*heigth
= 4*pi*(2.5)^2 + pi*5*2
= 109.9
that is the surface area of a bar soap 109.9 cm^2
