Lateral surface area is the area that can be seen from the solid, while total surface area includes the region that can't be seen on the solid. For example in cylinder: LSA = pi*r*l while, TSA = 2pi*r^2 + pi*r*l .
Answer:
1) 8.9 cm
2) 44.5 cm^2
Step-by-step explanation:
a) we want to calculate the length of the arc
Mathematically, we use the formula for the length of an arc
That will be ;
theta/360 * 2 * pi * r
theta = central angle = 51
r is radius = 10 cm
so we have ;
51/360 * 2 * 22/7 * 10 = 8.9 cm
2) The area of the sector is;
theta/360 * pi * r^2
51/360 * 22/7 * 10^2
= 44.5 cm^2
Monthly mortgage payment multiplied by 12 months in a year.
765*12=9,180.
Add yearly mortgage plus property taxes:
9,180+4,056=13,236
Divide the total by 12 months in a year.
13,236/12=1,103
You should charge $1,103 a month to come out even.
You can also take the property taxes and divide them by 12 (months in a year) 4056/12=338. Then add the monthly mortgage ($765)
765+338= $1,103.
Hope this helps :)
