8x2=16, 16 over 3 is roughly 5.33. so 5 is roughly 2/3rds of 8. Use basic cross multiplication
Answer:
42 m
Step-by-step explanation:
l+1 * (b+1) = lb+22
lb+b+l+1 = lb+22
l+b=21
perimeter = 42 m
Volume of Solids
The volume of the solid is 758.83 in³
Step-by-step explanation:
Given that the cone and half sphere is hollow
The volume of the cone = 
The Volume of the sphere = 
So the Volume of the half sphere =
The volume of solid = volume of cone + volume of the half sphere
Given
height h = 19 in
radius r = 5 in
= 
= 1/3 × 3.14 × 5 × 5 × 19
= 497.16 in³
= 2/3 × 3.14 × 5 × 5 × 5
= 261.67 in³
V = 497.16 in³ + 261.67 in³
= 758.83 in³
Hence the volume of the solid is 758.83 in³
First would be Red Marbles Second would be Blue and last Yellow. (remember this is <em><u>not</u></em> exact)
I'm sure this is good! :D
Answer:
a is drawn to scale, b isn't drawn to scale
Explanation:
a is drawn to scale because 10 cm=5 cm*2 and if measure it that side is exactly two of the 5 cm side. for the 25 cm it should be the same length as the 5 cm side and 20 cm side altogether. B isn't drawn to scale because the 40 cm side should be double the length of the 20 cm side, but it's less than the double the 20 cm side.
