The circumference of a circle is 9 pi m. What is the area, in square meters? Express
Ksivusya [100]

Answer:

20.25 m²

Step-by-step explanation:

the area (A) and circumference (C) of a circle are calculated using the formulae

C = 2πr and A = πr² ( where r is the radius )

calculate the radius using the formula for circumference

2πr = 9π ( divide both sides by 2π )

r =  =  = 4.5, hence

A = π × 4.5² = 20.25π m²

Please help me with this I need to find out what y is
julsineya [31]

Answer:

26°

Step-by-step explanation:

<DFG+<EFG = 180°( Being sum of adjacent angle in linear pair is 180°)

You can also write;

<DFG+<EFG = 180°( Being sum of supplementary angle is 180°)

By putting the value of those angles;

5y+3+(2y-5)=180

5y+3+2y-5=180

5y+2y-5+3 =180°

7y-2=180°

7y=180+2

7y=182

y=182/7

y=26°

Hence,

The value of y is 26°
