Answer:
Thanks mate.
Step-by-step explanation:
Hello there.
Question: <span>The diameter of a circle is 19 inches. Using the formula C ≈ 3d, what is the approximate circumference of the circle?
Answer: The formula is stating that the circumference is approximately equal to 3 times the diameter.
If the diameter is 19 in then to figure out the approximate value of the circumference you need to multiply it by 3.
19 x 3 = 57.
The circumference is approximately 57 in.
Hope This Helps You!
Good Luck Studying ^-^</span>
Answer:
The number could be 50.
Step-by-step explanation:
50/5 = 10
Answer:
x =4.58
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
x^2 + 10 ^2 = 11^2
x^2 +100 =121
x^2 = 121-100
x^2 =21
take the square root of each side
sqrt(x^2) = sqrt(21)
x =4.582575695
To the nearest hundredth
x =4.58
Answer:
the diameter, d, must be 6
Step-by-step explanation:
Formula for circumference of a circle with diameter d is C = πd.
If C = 6π = πd, then the diameter, d, must be 6.
