The area of a circle can be found using:
pi x r^2 (where r is the radius)

If the area of the circle is 255pi, then:
pi x r^2 = 255pi

Now we need to make r the subject:

r^2 = 255 (cancel the pi on both sides)

r = square root of 255

r = 15.96871942

Answer: 15.96871942 feet
Hope the answer helps :)

vlabodo [156]

To withdraw money from the automated teller machine the numeric pattern required to complete the personal ID numbers is 2, 13, 24, 35,46,57,68.

As given in the question,

Using automated teller machine customers at the bank withdraw money

Numeric pattern given for the personal ID numbers is

2, 13, 24, 35

First term 'a'= 2

Common difference between consecutive terms are same

'd'=13 -2                                                  

   =11

It is an arithmetic progression series

nth term = a+ (n-1)d

5th term = 2 +(5-1)11

               =46

6th term =2+(6 -1)11

              =57

7th term= 2+ (7-1)11

             = 68

Therefore, to withdraw money from the automated teller machine the numeric pattern required to complete the personal ID numbers is 2, 13, 24, 35,46,57,68.

The complete question is:

The customers at the bank would like to withdraw money from the automated teller machine. Help them enter their personal ID numbers by completing the numeric patterns. 2, 13, 24, 35, ___, ___, ____.

Please help! i don't know what to do, my formulas are not working for me. If anyone could please help i would really appreciate
Burka [1]

Answer:

  • The radius is r = 3 in,
  • The height is h = 4 in

<u>The area of the base:</u>

  • A(b) = πr² = π(3²) = 9π in²

<u>The circumference of the base:</u>

  • C = 2πr = 2π(3) = 6π in

<u>The area of the lateral surface:</u>

  • A(l) = Ch = 6π(4) = 24π in²

<u>The surface area:</u>

  • S = 2A(b) + A(l) = 2*9π + 24π = 42π in²

Use ABC to find the value of cos a. 24/7 7/24 7/25 24/25
ExtremeBDS [4]

Answer:

\frac{24}{25}

Step-by-step explanation:

using the cosine ratio;

\cos(\theta)= \frac{adjacent}{hypotenuse}

From the question, the side of the right angle triangle that is adjacent to the measured <a,(i.e BAC) is AC=24 and the hypotenuse is AB=25

This implies that,

cos(a)= \frac{24}{25}
