28 mm all you have to do is add 6+6+8+8 that’s what it looks like( sorry if this doesn’t work

Answer:

Step-by-step explanation:

square: 6mm * 6mm = 36mm

triangle 1: (8mm * 6mm) 0.5 = 24mm

triangle 2: (8mm * 6mm) 0.5 = 24mm

add all of it up to get the entire area

36 + 24 + 24 = 84

If the radius and the slant height of this right circular cone are each multiplied by 4, by what factor is the surface area multiplied?

Answers

Answer:

Step-by-step explanation:

Total surface area of a cone T1 = πr(r+l)

If the radius and the slant height of this right circular cone are each multiplied by 4, the new surface area will be expressed as;

T1 = π4r(4r+4l)

T2 = 16πr(r+l)

Taking the ratio of both total area

T1/T2 = πr(r+l)/16πr(r+l)

T1/T2 = 1/16

16T1 = T2

T2 = 16 T1

Hence the total surface area is multiplied by a factor of 16

Step-by-step explanation:

You deposit $300 in a savings account. The account earns 2% simple interest per year.
a. What is the interest earned after 10 years?
The interest earned is $ after 10 years.
b. What is the balance after 10 years?
The balance is $ after 10 years.

Answers

Answer:

Answer:

a. ----> $10

b. ----> $110

Step-by-step explanation:

principle ( p ) = $100

time ( t ) = 10 years

rate ( r ) = 11%

simple interest = (p × r × t)÷ 100

= ( $100 × 11 × 10 )÷ 100

= 11000 ÷ 100

= $110

interest = simple interest - principle

interest = $110 - $100

= $10

What is “F” in this triangle problem thingy

Answers

Answer:

f=43

Step-by-step explanation:

Hey There!

So if you didn't know the exterior angle (aka f) is equal to the sum of the opposite interior angles

so essentially what i am saying is that

19+24=f

19+24=43

therefore

f=43

hope this helps :)

if you have anymore questions just let me know

The sum of angles inside the Troy should be 180
19+24= 43
180-43=137
180-137=43
