Joel is going to make candles. He will pour melted wax into moulds.
Each mould is in the shape of a cylinder with diameter 12 cm and height 18 cm.
Joel has 15 kg of solid wax.
He knows that 1 kg of solid wax makes 1170 cm3 of melted wax.
To make each candle, Joel will pour melted wax into a mould to
7/8 of the height
of the mould.
He wants to make as many candles as he can.
How many candles can Joel make when using 15 kg of solid wax?
You must show your working.​

$12. that is my answer.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
