Answer:
The answer is 4.
Step-by-step explanation: To get the variable you do the opposite operation. So for this question you would do the opposite of subtraction which is addition. So you would add 5 to -1 and get 4.
Answer:
The surface area of the sphere is 576π u²
Option D.
Step-by-step explanation:
First of all we need to calculate the radius
To calculate the radius of a sphere we have to use the following formula:
V = volume = 2304π u³
r = radius
π = pi
V = ⁴⁄₃πr³
we replace with the known values
2304π u³ = ⁴⁄₃ * π * (r)³
2304π u³ / (⁴⁄₃ * π) = (r)³
1728 u³ = (r)³
1728 u³ = (r)³
³
√(
1728 u³) = r
12 u = r
The radius of the sphere is 12 u
Now we can find the surface area
To calculate the area of a sphere we have to use the following formula:
A = area
r = radius = 12 u
π = pi
A = 4πr²
we replace with the known values
A = 4 * π * (12 u)²
A = 4 * π * 144 u²
A = 576π u²
The surface area of the sphere is 576π u²
Answer:
Length = 0.8m
Breadth = 0.3m
Volume = 108litres = 108÷1000 = 0.108m³
Volume = l x b x h
0.108 = 0.8 x 0.3 x h
0.108 ÷ ( 0.8 x 0.3 ) = h
0.45 = h
Answer:
12z - 3
Step-by-step explanation:
12z - 3=0
+3 +3
12z=3
/12 /12
z=1/4
Answer:
⅓
Step-by-step explanation:
33⅓% is:
(33×3+1)/3 = 100/3 %
To convert percentage into decimals, divide by 100
100/300
1/3
