Answer:
42 candles
Step-by-step explanation:
Firstly, we need to find the surface area of the pyramid used. This can be obtained by finding the area of the base, multiplied by the height of the pyramid.
The area of the base since it is rectangle is L * B and that is 5 * 2 = 10cm.sqr
The volume of the pyramid is A * h and that is 10 * 12 = 120cm.cub
To fInd the number of candles used , we simply divide the volume of wax by the volume of a candle.
That is 5040/120 = 42 candles
This is the formula to determine the length of arc
length of arc = angle/360° × circumference
First we should find the circle circumference
c = 2 × π × r
c = 2 × 3.14 × 6
c = 37.68 miles
Second find the length of arc
length of arc = angle/360 × circumference
length of arc = 135/360 × 37.68
length of arc = 3/8 × 37.68
length of arc = (3 × 37.68)/8
length of arc = 113.04/8
length of arc = 14.13
The length of arc is 14.13 miles
