Use the std eqn of a circle with center at (h,k) and radius r:

(x-0)^2 + (y+2)^2 = 9^2, or just x^2 + (y+2)^2 = 9^2.

The figures are similar. Find the area.
Crazy boy [7]

Answer:

108 in

Step-by-step explanation:

The figures are similar, so if we find a relation of the area and the diagonal in rectangle 1  we can apply it to rectangle 2.

rectangle 1 :

72/x=12

x=6

therefore

72/6=12

rectangle 2:

A/x=18

A/6=18

6*18=108

A=108 in

Hope this helps

Find the lateral area of a cylinder with the given measurements. Use 3.14 for pi and round your answer to the nearest tenth.

height: 15 centimeters

radius: 9 centimeters

Question 11 options:

787.3 cm2

1356.5 cm2

847.8 cm2

889.9 cm2

So we know the formula for the lateral area of a cylinder is:

AL=2πrh

now all we have to do is put the given value in place of the correct variable then solve like so:

AL=2*3.14*9*15

AL= 847.8 cm2

so the answer is the third option

hope this helps

How many ounces of pure gold are in an 18 karat gold chain that weighs 2.8 ounces?
Delvig [45]
Pure gold is 24 Karat's so the ratio of purity 18 karat gold is:
(Number of Karats of Gold chain)/(Number of Karats of pure Gold)
this will give us:
18/24
=3/4 
The weight of pure gold in 18 Karat Gold will be:
(ratio of purity)×(Total weight of chain)
=3/4×18
=13 1/2 ounces
=13.5 ounces.
