Answer:
C
Step-by-step explanation:
Equation for density is mass/volume
Mass=22.62 g
Volume= 22/7 x 1/2^2 x 4
3.14 x 0.5 x 0.5 x 4
=3.14 cm3
Mass/ Volume
22.62/3.14
7.2 g/cm3 is the answer
Answer: Right and isosceles
Answer: a= 120
Step-by-step explanation:A = height times width, 10 times 12 is 120 :)
2. Each side of a pentagon is the same size.
4cm x 5 = 20cm or 4cm+4cm+4cm+4cm+4cm = 20cm
3. Each side of a square is the same size.
13yd x 4 = 52yd or 13yd+13yd+13yd+13yd = 52yd
4. Add all sides together.
12m+12m+30m+30m = 84m
5. Again add all sides together.
16yd+16yd+4yd+4yd = 40yd
6. Each side of a square is the same size.
7in x 4 = 28in. or 7in+7in+7in+7in = 28in
7. Add all sides together.
2cm+2cm+3cm+3cm = 10cm
8. Each side of a rhombus is the same size. A rhombus has 4 sides.
23in x 4 = 92in or 23in+23in+23in+23in = 92in
9. A regular octagon has 8 sides and each side is the same size.
9cm x 8 = 72cm
