Answer: 8. 75% = 75/100 = 3/4

(3/4)*80 = 3 *20 = 60

18. 10% = 0.1

Amount of real fruit juice = 64 * 10%

= 64 * 0.1 = 6.4 ounce

I think you’re asking for the circled questions.
8. 75% = 75/100 = 3/4
(3/4)*80 = 3 *20 = 60

18. 10% = 0.1
Amount of real fruit juice = 64 * 10%
= 64 * 0.1 = 6.4 ounce

In the given figure find the area of the shaded region if AC = 24 CM AB = 7cm and O is the centre

wariber [46]

See the attached figure to better understand the problem

we know that

<span>The inscribed angle in a circle measures half of the arc it comprises.

</span>in this problem
the inscribed angle= ∠ACB
and the arc it comprises measures 180°
then
the ∠ACB=180°/2-------> ∠ACB=90°

<span>applying the Pythagorean theorem
</span>AC²+CB²=AB²-------> AB²=24²+7²-------> AB²=625------> AB=25 cm

the diameter of circle is AB
radius=25/2--------> r=12.5 cm

[the area of a half circle]=pi*r²/2------> pi*12.5²/2--------> 245.44 cm²

[area of triangle ABC]=AC*CB/2--------> 24*7/2-------> 84 cm²

[the area of the shaded region]=[the area of a half circle]-[area of triangle ABC]

[the area of the shaded region]=245.44-84-------> 161.44 cm²

the answer is
the area of the shaded region is 161.44 cm²
