The area of a circle is 153.86 square meters. What is the diameter of a circle?

Mathematics
1 answer:
levacccp [35]3 years ago
7 0

Answer:

7.8 (when I calculated I rounded to tenths so the actual answer might be a little bit different)

Step-by-step explanation:

the area of a circle is radius squared so

153.86= radius squared

sqaure root both sides and you get 12.4 =radius

divide both sides by pi and you get 3.9 which is the radius

the diameter is double the radius which is 3.9 *2 which is  7.8 :) hope this helped.

Write a simplified polynomial expression in standard form to represent the area of the rectangle below.
Burka [1]
Area of Rectangle = length times width
lets say length = 2x-4
width = x+5

Note: you can switch these around, width could be 2x-4 and length could be x+5, it doesnt matter.

With that being said:
length * width = area
(2x-4)(x+5)=area
FOIL (First Outer Inner Last)
2x^{2}+10x-4x-20=area
Simplify:
x^{2}+6x-20=area

-2(11-12x)= -4(1-6x)
GalinKa [24]

The given equation -2(11 - 12x) = -4(1 - 6x) has infinite solutions

<u><em>Solution:</em></u>

Given that we have to solve the given expression

Given expression is:

-2(11 - 12x) = -4(1- 6x)

We have to use distributive property to solve the given expression

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

Which means,

a(b + c) = ab + ac

Apply this in given expression

-2(11 - 12x) = -4(1-6x)

-22 + 24x = -4 + 24x

When both sides of the equation are simplified, the coefficients are the same, then infinite number of solutions occur

If we end up with the same term on both sides of the equal sign, such as 24x = 24x, then we have infinite solutions

Connor is stuck in a traffic jam on a single-lane road. The traffic report tells him the traffic jam stretches for 5.5 miles. If
dedylja [7]

Answer:

2323

Step-by-step explanation:

According to the questions above, the report from the traffic jam says the traffics jam stretches for 5.5 miles

As Connor assumes that each car is about 12.5 long

The next step is to convert 5.5 miles into feet.

Since 1 mile = 5280

To convert 5.5 miles, 5.5 x 5280 = 29040 feet  

To find the numbers of cars struck in traffic, we will have to divide 29040 by 12.5

29040/12.5 = 2323.3 ≅ 2323
