Answer:
Step-by-step explanation:
Given:
°
From the triangle, using the theorem that center angle by an arc is twice the angle it subtend at the circumference.
Also, the diameter of the circle is BD. As per the theorem that says that angle subtended by the diameter at the circumference is always 90°,
From the Δ BCD, which is a right angled triangle,
Now, using the theorem that angle between the tangent and a chord is equal to the angle subtended by the same chord at the circumference.
Here, chords CD and BC subtend angles 40 and 50 at the circumference as shown in the diagram by angles 
and EF is a tangent to the circle at point C.
Therefore, 
Again, using the same theorem as above,
Hence, all the angles are as follows:
1 means that he is present, 0 means that he is not.
True means that they can open.
Each candle in the set is a different size.
The smallest candle has a radius of 0.5 inches and a height of 3 inches.
The other two candles are scaled versions of the smallest, with scale factors of 2 and 3.
How much wax is needed to create one set of candles?
in cubic inches
Answer
pi 0.5^2 *3 = 0.75pi is the volume of the first candle.
The second volume is 8 * 0.75pi = 6pi.
And the last volume is 27 * 0.75 pi = 20.25 pi So in total we just take the sum and that is 27pi
Answer:
c. an algorithm
Step-by-step explanation:
Most math problems are best solved using an algorithm. Certainly, converting numbers from one form to another is easily done that way.
_____
The integer part is the whole-number quotient of the division. The fractional part is the remainder divided by the denominator:
39/8 = 32/8 + 7/8 = 4 7/8
12% of an item purchased at $380 is equal to $45.60 you will pay $334.40
