The first one is right and the third one is right, but you need to switch the 15% and the 95%.
In #2, it's asking for the kids that <em>are not</em> Michael, so it'd be 18/19. Which is then rounded to roughly 95%.
#4 asks for 6/40 = 15%
Answer:
17
Step-by-step explanation:
14 - 7 = 7
7 + 4 +9 =20
20 - 3 = 17
Answer:
V = 5626.88 mm³
Step-by-step explanation:
radius r = 8 mm
height h = 28 mm
volume V = 5626.88 mm³
lateral surface area L = 1406.72 mm²
top surface area T = 200.96 mm²
base surface area B = 200.96 mm²
total surface area A = 1808.64 mm²
In Terms of Pi π
volume V = 1792 π mm³
lateral surface area L = 448 π mm²
top surface area T = 64 π mm²
base surface area B = 64 π mm²
total surface area A = 576 π mm²
Formula: Calculate volume of a cylinder:
V = πr²h
r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
Answer:
-33.
Step-by-step explanation:
[12 -5 x 9]
= 12 - 45
= -33.
