Answer:
16= 4²
25= 5²
36= 6²
49= 7²
64= 8²
81= 9²
so, third option is correct I.e. 49
hope it will help....
Answer:
y = 2x + 11
Step-by-step explanation:
Parallel means the two lines have the same slope. The slope = 2 because the two is in front of the x. Whatever number is in front of the x is the slope.
So far what you know is
y = 2x + b
The point (-3,5) is what you need to get b.
y = 2x + b
y = 5
x = - 3
5 = -3(2) + b
5 = -6 + b
b = 5 + 6
b = 11

Step-by-step explanation:
Given that:
Volume of cylinder, V= 87.92 cm³
Radius, r= 2 cm
π=3.14
Formula for volume of cylinder:
V=πr²h
Put values in the formula.
87.92=(3.14)(2)²h
87.92=(3.14)(4)h
87.92=12.56h
Divide both sides by 12.56
7=h
or
h=7 cm
Answer: Height of Cylinder is 7 cm.
Answer: The answer is 314.28 cm² (approx.).
Step-by-step explanation: Given that an engineer is going to install a new water pipe. The diameter of this circular pipe is, d = 20 cm.
We need to find the area 'A' of the circular cross-section of the pipe.
Given, diameter of the circular section is
So, the radius of the circular cross-section will be
Therefore, cross-sectional area of the pipe is
Thus, the answer is 314.28 cm² (approx.).
