<h3>Answer:   200.96 ft^2  (choice C)</h3>

=======================================================

Work Shown:

A = pi*r^2

A = 3.14*8^2

A = 200.96

Note that the radius r = 8 is half of the diameter d = 16. I'm using the approximation pi = 3.14, which means the area is approximate. To get a more accurate answer, use more decimal digits of pi. The units of the area are in square feet, which can be written as "sq ft" or as "ft^2".

Number of gallons of gas. Miles driven 0 0 2 62 4 124 10 310 How many gallons are used when the car has been driven 18 miles
Goryan [66]

558 gallons are used when the car has been driven 18 miles.

<u>Step-by-step explanation:</u>

<u>From the given data, it can be determined that :</u>

  • The number of gallons for 2 miles = 62 gallons
  • The number of gallons for 4 miles = 124 gallons
  • The number of gallons for 10 miles = 310 gallons

Let, the number of gallons for 18 miles = 'x' gallons

<u>To find x :</u>

compare the given data with the unknown data,

62 gallons / 2 miles = x gallons / 18 miles

keep x alone on one side,

x = (62×18) / 2

x = 31×18

x = 558 gallons

Therefore, 558 gallons are used to drive 18 miles.

Based only on the information given in the diagram, which congruence
Wewaii [24]

Answer:

Option B

Option E

Step-by-step explanation:

By the use of following postulates we can prove the two right triangles to be congruent.

1). HA - [Equal hypotenuse and an cute angles]

2). LL - [Two legs should be equal]

3). LA - [One leg and one angle must be equal]

4). ASA - [Two angles and the side containing these angles should be equal]

In the given right triangles,

1). OJ ≅ IL

2). ∠O ≅ ∠I

3). ∠J ≅ ∠L

Therefore, two postulates HA, ASA will be applicable for the congruence of the two triangles given.

Options A and E will be the answer.
