Answer:
shaded area = 113.64 cm²
Step-by-step explanation:
To find the shaded area, subtract the area of the circle from the area of the triangle.
Area of a triangle = 1/2 x base x height
⇒ area of triangle = 1/2 x 25 x 21.4 = 267.5 cm²
Area of a circle = (where r is the radius)
From inspection, we can see that the diameter of the circle = 14 cm
Therefore, as the diameter = 2r, then r = 14 ÷ 2 = 7 cm
⇒ area of circle = 3.14 x 7² = 153.86 cm²
Shaded area = area of triangle - area of circle
⇒ shaded area = 267.5 - 153.86 = 113.64 cm²
Answer:
Up to 10
Step-by-step explanation:
- Cost of fish = $3.99
- Limit of money = $40
- Number of fish = x
<u>Inequality:</u>
- 3.99x ≤ 40
- x ≤ 40/3.99
- x ≤ 10.02
That is the exact representation of the constant π. By definition:
π=C/d, where C is the circumference of a circle and d is the diameter.
Answer:
18in^3
Step-by-step explanation:
v=<u>πr^</u><u>2</u><u>h</u>
3
where π =3
diameter=3
,r=<u>3</u>
2
=1.5
h=8
v= <u>3</u><u>×</u><u>1</u><u>.</u><u>5</u><u>×</u><u>1</u><u>.</u><u>5</u><u>×</u><u>8</u>
3
v= 18
When you multiply a natural number with an integer it makes the sum negative but if you multiply two integers it makes the sum positive
