Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2
Volume equals width times height times length
Answer:
126 degree
Step-by-step explanation:
use alternate angles and linear pair
Answer:
The answer is 9 or 8 because they both are on the same fx
Answer:
tall candles = 39
Short candles = 52
Step-by-step explanation:
let tall candles be x
and short candles be y
No. Of candles sold = x + y =91
Money made from candles will be equal to = 8x + 5y = $572
These both are simultaneous linear equations.
x + y =91 ( multiply by 5)
5x + 5y = 455
8x + 5y = $572
Subtract them:
-3x = -117
x = -117/3
x = 39
put value of x in
x + y = 91
39 + y = 91
y = 91 - 39
y = 52
x shows tall candles so they are 39
y shows short candles so they are 52
