Answer:
The larger circle has an approximate area of 314 cm²
Step-by-step explanation:
As you can see by the diagram, the white circle is twice as wide as the grey circles. That means that its radius is also twice theirs.
The grey circles have a radius of 5cm, so the larger has a radius of 10cm.
The radius of a circle is equal to πr², where r is the radius of the circle. So the larger circle's radius is:
π × 10²
≈ 3.14 × 100
= 314.
So the larger circle has an approximate area of 314 cm²

A column vector has the form [tex]\left[\begin{array}{ccc}x\\y\\\end{array}\right][/tex]
Following the direction of the arrow , the x- displacement = - 3 and y- displacement = 2 , then column vector is
[tex]\left[\begin{array}{ccc}-3\\2\\\end{array}\right][/tex]
h + k
= [tex]\left[\begin{array}{ccc}4\\-3\\\end{array}\right][/tex] + [tex]\left[\begin{array}{ccc}-2\\-1\\\end{array}\right][/tex] ← add corresponding elements from each vector
= [tex]\left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right][/tex]

A kite is flying at a height of 65 m attached to a string. If the inclination of the string with the ground is 31°, find the length of string.
Show your work please
Answers
Answer:
let KL be the string PL be perpendicular distance between them. and KL be height of kite flying.
in right angled triangle
relationship between perpendicular and hypotenuse is given by sin angle
sin 31°=p/h
h=65/sin31
KP=126.2m
the length of string is 126.2m
Answer:
127.45 m
Step-by-step explanation:
Given :-
Height of kite = 65 m .Inclination of string = 31° .To Find :-
The length of the string .Solution :-
Here we need to find out the length of the string here if we imagine a right angle triangle in which the height of the kite will be the perpendicular of the triangle and the length of the string will be the hypotenuse of triangle .
And the angle between the the string and the ground will be 31°.
Here we can use ratio of sine as ,
> sin∅ = p/h
> sin 31° = 65m/ h
> h = 65m/sin 31°
> h = 65m/0.51
> h = 127 .45 m
The length of each side of a cube is x + 1 inches. What is the volume of the cube in cubic inches?
Answers
Answer:
V = x³ + 3x² + 3x + 1 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side ) , then
V = (x + 1)³
= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL
= (x + 1)(x² + 2x + 1) ← distribute
= x³ + 2x² + x + x² + 2x + 1 ← collect like terms
= x³ + 3x² + 3x + 1

Formula:
V = πr^2h
V = 3.14 * 4.5^2 * 8
V = 3.14 * 20.25 * 8
V = 508.68 ft^3
508.68 rounded to the nearest whole number is 509
So the volume of the cylinder is 509 ft^3
