Answer: 21.994 cm²

Step-by-step explanation:

Area of the shaded region = Area of the bigger circle - the areas of the two smaller circles.

Formula for finding area of a circle = πr² where π is a constants . It has value of 22/7 or 3.142

Now area of the bigger circle = 3.142 x 3²

= 3.142 x 9

= 28.278 cm² Now are of the two smaller triangle = 3.142 x 1² x 2

= 6.284 cm².

Therefore are of the shaded region = 28.278 - 6.284

= 21.994 cm²

_30. Solve the following logarithmic equation: log8(x + 9) + 3 = 3

Bezzdna [24]

Answer:

Step-by-step explanation:

using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$

$log_{8}$ (x + 9) + 3 = 3 ( subtract 3 from both sides )

$log_{8}$ (x + 9) = 0 , then

x + 9 = $8^{0}$ = 1 ( subtract 9 from both sides )

x = - 8
