-5 is the smallest. I will put them in order for you (smallest to greatest) -5, -1, 2, 3, 6, 14, 18
We know that
scale factor=1/4
so
volume of the smaller pyramid=[scale factor]³*volume original pyramid
volume original pyramid=192 unit³
volume of the smaller pyramid=[1/4]³*192---> (1/64)*192----> 3 units ³
the answer is
3 units³
Answer:
D. 154
Step-by-step explanation:
The area of the rectangle is 15*5= 75 inches
The area of the 2 semicircles combined, which make a circle, are:
π*r², where r is 5
r²=25
π*25=78.53981633
75 + 78.53981633 is about 154
3x-13=305
3x=305+13
3x=318
(3x)÷3=318÷3
x=106
check.. (3×106)-13=305
318-13=305
305=305
