Answer:
Rational
Step-by-step explanation:
-9 is rational because 9 is a perfect square and all perfect squares are rational.
Answer:
Step-by-step explanation:
Recall the mnemonics SOH CAH TOA.
SOH means the Sine ratio is Opposite over Hypotenuse.
This implies that;
The side opposite to angle A is 4cm and the hypotenuse is 5cm.
Answer:
radius = 5 units
area of a circle = 15.7units²
Step-by-step explanation:
given that the circumference of a circle = 31.4
radius = ?
recall that the formulae for finding the circumference of a circle = 2πr
circumference of a circle = 2 x 3.14 x r
31. 4 = 6.28r
divide both sides by the coefficient of r which is 6.28
31.4/6.28 = 6.28r/6.28
5 = r
radius = 5 units
therefore the radius of the circle whose circumference is 31.4 units is evaluated to be 5units
to find the area of the circle
recall the formula = πr²
area of a circle = 3.14 x 5²
area of a circle = 3.14 x 25
area of a circle = 15.7units²
Answer:
Below.
Step-by-step explanation:
15+10+8=33.
The value of x is 14
<h3>How to solve for x?</h3>
From the question, the lines from the center of the circle to the chords have equal measures of 9 units
This line divides a chord into equal segments, where each segment is 7 units
So, we have:
x = 7 + 7
Evaluate
x = 14
Hence, the value of x is 14
