For the first one write 9 divided by 2 gives your your radius an it’s 3.5. the formula is 2 x 3.14 x radius and that gives you 21.98.
the 2nd one is 2 x 3.14 x 9 = 56.52
the 3rd is 2 x 3.14 x 5= 31.4
formula is always 2 x 3.14 (or pie) x radius
to get your radius from your diameter you do your diameter divided by 2
Answer:
The x intercept is given by, (-3 , 0)
Step-by-step explanation:
The given equation from the graph is,
4x = 12 + y --------------(1)
Putting y = 0 we get,
x =
= - 3
Hence, the x intercept is given by, (-3 , 0)
Answer:
c = 25
Step-by-step explanation:
Using the Pythagorean rule which states that for a right angle triangle, the square of the hypotenuse equals the sum of the squares of the other two sides.
The hypotenuse is the longest side and it is always the side opposite to the right angle.
In this case, c is the hypotenuse
Now let's solve for c
c^2 = 24^2 + 7^2
c^2 = 576 + 49
c^2 = 625
c =
c = 25
