LenKa [72]

Answer:

Step-by-step explanation:

∠ADC = 90°

∠ADB + ∠BDC = 90

20 + ∠BDC = 90

∠BDC = 90 - 20 = 70

∠BDC = 70°

16) ∠PSR = ∠PSQ +∠QSR

= 60 + 10

= 70

18) ∠PSR = 130

∠PSQ + ∠QSR = 130

90+ ∠QSR = 130

∠QSR = 130 - 90

∠QSR = 40

19)∠ADC = ∠ADB + ∠BDC

= 120 +20

= 140

20) ∠PSR = 125

The figure below shows a circular lawn. Its diameter is 26ft. 26ft (a) Use the calculator to find the area and circumference of

attashe74 [19]

The area and the circumference of the circle are 530.93 square ft and 81.68 ft. If fertilizer will be applied to the lawn. Then the area is used. If the lawn will be surrounded by tape. Then the circumference is used.

<h3>What is a circle?</h3>

It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

The figure below shows a circular lawn. Its diameter is 26 ft.

Then the area of the circle will be

$\rm A = \dfrac{\pi }{4} d^2\\\\A = \dfrac{\pi }{4} \times 26^2\\\\A = 530.93 \ \ ft^2$

Then the circumference of the circle will be

Circumference = π d

Circumference = π × 26

Circumference = 81.68 ft

If fertilizer will be applied to the lawn. Then the area is used.

If the lawn will be surrounded by tape. Then the circumference is used.

Mr.chan made 252 cookies for the annual fifth grade class bake sale . they sold 3/4 of them and 3/9 of the remaining cookies wer

Eva8 [605]

So, personally I would take 252 and divide it by 4. this will give you 63 which is 1/4 of the cookies. Then add that 63 three times to get a total of 189 cookies which would be your 3/4 sold. so since there is only 63 cookies left then you would go into your final problem. 3/9 is equal to 1/3, so all you would do is divide 63 by 3 and get a total of 21 cookies given to the pta.
