Answer:

36πin²

Step-by-step explanation:

Area of a circle: $A=\pi r^2$

r - radius

We are given the diameter of the circle. The radius is half the diameter.

12/2 = 6

The radius is 6cm.

$A=\pi (6)^2\\\\A=\pi 36\\\\\boxed{A=36\pi }$

The area of the circle is 36πin².

Hope this helps.

Hi pls help me thanksss<br>pls provide me with workings thankss :)

Vinil7 [7]

Step-by-step explanation:

(i)

Using cos(a - b) = cos a cos b + sin a sin b

$\frac{4}{5}$ = cos a cos b + $\frac{1}{5}$

cos a cos b = $\frac{4}{5} -\frac{1}{5} = \frac{3}{5}$

(ii)

Using cos(a + b) = cos a cos b - sin a sin b

cos(a + b) = $\frac{3}{5}-\frac{1}{5}=\frac{2}{5}$

(iii)

Using cot a = $\frac{cos a}{sin a}$

$=(\frac{cos A}{sin A} )(\frac{cos B}{sin B} )$

$=\frac{cos A cos B}{sin A sin B}$

$=\frac{\frac{3}{5} }{\frac{1}{5} }$ $=\frac{3}{5}$ × $5$

= 3

please give me a brainliest answer

Paula has 4 bananas. She wants to divide each of them into 1/6 sections. How many 1/6's are there in 4 bananas?

k0ka [10]

Answer:

There are 24 1/6-banana sections in 4 bananas.

Step-by-step explanation:

Here we need to divide 4 bananas into 1/6 banana sections. Dividing 4 bananas by 1/6 is equivalent to multiplying 4 bananas by 6/1:

(4)(6)

-------- = 24

There are 24 1/6-banana sections in 4 bananas.

110% OF WHAT NUMBER IS 880? SHOW EVERY STEP PLZ:)

Nookie1986 [14]

So 110% of x is 880 means 1.1x=880

so 1.1x=880
multiply both sides by 10
11x=8800
divide both sides by 11
8800=88 times 100 88=8 times 11
8800/11=800
x=800
