Ithink it's 50 now a barrel of tomato sauce has spilled on a tile floor. the sauce flow can be expressed with the function r(t) = 2t, where t represents time in minutes and r represents how far the sauce is spreading. the spilled sauce is creating a circular pattern on the tile. the area of the pattern can be expressed as a(r) = πr2. part a: find the area of the circle of spilled sauce as a function of time, or a[r(t)]. show your work. (6 points) part b: how large is the area of spilled sauce after 5 minutes? you may use 3.14 to approximate π in this problem. (4 points)

Here barrel of tomato sauce has spilled on a tile floor.

The function represents how the sauce is flowing, where, 't' represents time in minutes, and 'r' represents how far the sauce is spreading.

The spilled sauce is creating a circular pattern on the tile and the area of pattern is expressed as

A. Now we have to find the area of circle of spilled sauce as a function of time:

.

Now, we know that

and

plugging the value of 'r' as function of time in the area of the pattern, we get:

So the area of the circular pattern as a function of time is given as:

B. We have to find how large is the area of spilled sauce after 5 minutes.

plugging the value of 't' in the equation of the area as a function of time,

we get:

(we have taken )

Therefore, square units

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
