Answer:

NO, the area of the circular base will not be 18.84 cm square.

Step-by-step explanation:

Given is that the radius of the cylinder is = 3 cm

We will calculate the area of the circular base.

The area of the circular base is given as : $\pi r^{2}$

Putting values in the formula we get:

$3.14\times3\times3=28.26$ cm square

So, The answer is - NO, the area of the circular base will not be 18.84 cm square.

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = $\sqrt{(4-(-1))^{2} + (-1-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

BC = $\sqrt{(0-(-1))^{2} + (-3-4)^{2} }$ = 5 $\sqrt{2}$ ≈ 7.1

CA = $\sqrt{(0-4)^{2} + (-3-(-1))^{2} }$ = 2 $\sqrt{5}$ ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

Answer:

The second choice $(7.6,8.8)$

Step-by-step explanation:

The missing image is attached

We use the section formula:

$(x,y)=(\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n})$

We substitute $x_1=3,x_2=16,y_1=2,y_2=21$ and m=5, n=9

$(x,y)=(\frac{5*16+9*3}{5+9},\frac{5*21+5*2}{9+5})$

We simplify to get:

$(x,y)=(\frac{80+27}{14},\frac{105+10}{14})$

This simplifies to:

$(x,y)=(\frac{107}{14},\frac{125}{14})$

In decimals we get:

$(x,y)=(7.6,8.8)$

You buy 21 lbs of cucumbers which are 92% water. A few days later they’re 85% water. How much do they weigh then?

IrinaK [193]

To solve this, you must find the initial weight of the cucumber. To do this, you must divide the weight by the percentage of water and multiply it by 100.

(21/92)×100=22.83lbs.

Then, you multiply it by 85% and divide it by 100. Or simply multiply it by 0.85.

22.83×0.85=19.41lbs.
