Find the area and the circumference of a circle with diameter 6 km

mash [69]

Answer:

$C= 18.84 \ km$

$A = 28.26 \ km$

Step-by-step explanation:

Circumference can be calculated using following formula

$C=2\pi r$ ------------(1)

and area of circle can be calculated using following formula

$A= \pi r^{2}$ ------------(2)

Here diameter d=6 km

Radius (r) is half of diameter

$r= \frac{d}{2} = \frac{6}{2} = 3 \ km$

Now calculate Circumference and diameter using equations (1) and (2) respectively

$C= 2\pi r = 2 (3.14) (3)\\C= 18.84 \ km$

$A= 3.14 (3)^2\\A= 28.26 \ km$

Please help -3/4(8n + 12) = 3(n-3)

Dennis_Churaev [7]

Step-by-step explanation:

$- \frac{3}{4} (8n + 12) = 3(n - 3)$

$- 3(8n + 12) = 12(n - 3)$

$\cancel{- 3}(8n + 12) = \cancel{12}(n - 3)$

$- (8n + 12) = 4(n - 3)$

$- 8n - 12 = 4n - 12$

$- 8n - 4n = - 12 + 12$

$- 12n = 0$

$n = 0$
