Answer: 5.29pi m^2

Step-by-step explanation:

The circumference = 2 * pi * radius

Therefore, the radius = circumference/(2pi)

Radius = 4.6pi/2/pi

Radius = 2.3meters

Area = pi*r^2

Area = pi*(2.3)^2

Area = 5.29pi m^2

The difference of 2 numbers is 3 and their sum is 25. What are the numbers? 10 and 15 14 and 11 11 and 13 13 and 12
vagabundo [1.1K]

Let the two numbers be x and y

As given, the difference of two numbers is 3, so

x-y=3  or x=3+y ....(1)

And their sum is 25, so

x+y=25   .....(2)

Putting x=3+y in equation (2)

3+y+y=25

2y=22

y=11

As, x+y=25

x+11=25

x=14

So the two numbers are = 14 and 11

if the HCF of 408 and 1032 is expressible in the form of 1032 into 2 + 408 into P then find the value of p​
alexandr1967 [171]

Answer:

below.

Step-by-step explanation:

408 = 2*2*2*3*17

1032 = 2*2*2*3*43

So the HCF is 2*2*2*3 = 24

24 = 2/1032 + p/408

24 - 2/1032 = p/408

p = (24 - 2/1032) * 408

p = 9791.21 to nearest hundredth.

If (X + 8) is a factor of f(x), which of the following must be true?
julsineya [31]

Answer: C

Step-by-step explanation:

If (X + 8) is a factor of f(x), then to find the root, equate the factor to zero. That is,

X + 8 = 0

X = 0 - 8

X = -8

If -8 is substituted into f(x), the equation will tend to zero. That is,

F( -8 ) = 0

C is therefore the correct answer.
