Answer:

16,080 km.

Step-by-step explanation:

We want the total number of kilometers in one year.

4 weeks /month.

for Work: 9 months in the year 60 km/day 5 days/week

Family Visit : 720 km for 4 times a year

Personal: 200 km / month

Work total = 60 km/day * 5 days/week * 4week/month * 9 months

WorkTotal= 60*5*4*9 = 10,800 km

FamilyTotal= 4*720 = 2880 km

Personal = 200*12 = 2400 km

Total = 10,800 + 2880 + 2400 = 16,080 km

Sergio works at a bakery and needs to cover

Elan Coil [88]

Answer:

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The surface area of the cylindrical cake is equal to the lateral area plus the area of the top of cylinder (remember that the bottom of the cake does not need frosting)

$SA=\pi r^{2}+2\pi r h$

we have

$r=40.2/2=20.1\ cm$ ---> the radius is half the diameter

$h=15.6\ cm$

$\pi=3.14$

substitute the given values

$SA=(3.14)(20.1)^{2}+2(3.14)(20.1)(15.6)$

$SA=1,268.59+1,969.16\\SA=3,237.75\ cm^2$

Round up to the nearest whole number

$SA=3,238\ cm^2$

therefore

The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
