What is the area of the square?
What’s the area of the circle

Answers

Answer:

Square: 144 m²

Circle: 113.04 m²

Step-by-step explanation:

The formula for area of a square: side × side.

The formula for area of a circle: r²π (radius × radius × pi)

**SQUARES HAVE EQUAL SIDES**

As shown in the photo, the side lengths of the square are 12.

side × side

12 × 12 = 144

Therefore, 144 m² is the area of the square.

-------------------------------------------------------------------------------------------------------------

The diameter of the circle is 12 as well.

But, to find the area of the circle, we need the radius.

To find the radius of a circle, divide the diameter by 2.

12 ÷ 2 = 6.

6 is the radius.

Now we plug the numbers into the equation.

**3.14 IS A SUBSTITUTE FOR PI**

r²π (radius × radius × pi)

6²π (6 × 6 × 3.14) = 113.04

Therefore, 113.04 m² is the area of the circle.

The radius of the hemisphere is 16 mm

length of the inclined sides are 20 mm

The perimeter of the figure is the sum of the length of two inclined sides and a semi-circle circumference

[tex]\Rightarrow \text{Perimeter P=}\dfrac{2\pi r}{2}+2\times 20\\\\\Rightarrow P=\pi \times 16+40\\\Rightarrow P=50.75+40\\\Rightarrow P=90.75\ mm[/tex]

|Calculate the midpoint (-5,5), K(-3,-2)

Answers

Answer:

(-4,1.5)

Step-by-step explanation:

Given :-

Two points (-5,5) and (-3,-2)

And we need to find out the midpoint of the two points. The midpoint of two points is given by the ,

[tex]:\implies[/tex] Midpoint =( x1+x2/2 , y1+y2/2)

[tex]:\implies[/tex] Midpoint =( -5-3/2 , 5-2/2)

[tex]:\implies[/tex] Midpoint =(-8/2,3/2)

[tex]:\implies[/tex] Midpoint = (-4 , 1.5)

Hence the midpoint of the two points is (-4,1.5) .
Explaination :

Here we would be using the midpoint formula to find the co-ordinates of the line segment joining the two given points.

Given points,

(-5,5) and (-3,-2)

Midpoint of two points:-

What is the diameter of a cone with height 8 m and volume 150 pi m3 ?
A. 7.5 m
B. 5V3 m
o C. 7.573 m
D. 15 m

Answers

Answer:

V = pi*r^2*h

V = 150 m^3

h = 8 m

150 = pi*r^2*8

Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.

V = 1/3 pi r^2 h

Diameter of the cone is 15 m. So, option D is correct.

What is meant by solid shape ?

Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.

Here,

Volume of the cone is given by,

 V = 150[tex]\pi[/tex] m³

Height of the cone, h = 8 m

We know, the equation for the volume of a cone is,

V = 1/3[tex]\pi[/tex]r²h

where r is the radius and h is the height of the cone.

So,

(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]

r²x 8 = 3 x 150 = 450

r² = 450/8

r² = 56.25

r = 7.5 m

Therefore, diameter of the cone,

d = 2r

d = 2 x 7.5

d = 15 m

Hence,

Diameter of the cone is 15 m.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.

A(n)=6+(n-1)(1/5)

Answers

Answer: a’(n)=1/5

Step-by-step explanation:

The first term is 6, the fourth term is 6.6, and the tenth term is 7.8 in the arithmetic sequence.

What is an arithmetic sequence?

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The given rule for the arithmetic sequence is:

A(n) = 6 + (n - 1)(1/5)

To find the first term, substitute n = 1 in the formula:

A(1) = 6 + (1 - 1)(1/5)

A(1) = 6 + 0

A(1) = 6

Therefore, the first term of the arithmetic sequence is 6.

To find the fourth term, substitute n = 4 in the formula:

A(4) = 6 + (4 - 1)(1/5)

A(4) = 6 + 3/5

A(4) = 6.6

Therefore, the fourth term of the arithmetic sequence is 6.6.

To find the tenth term, substitute n = 10 in the formula:

A(10) = 6 + (10 - 1)(1/5)

A(10) = 6 + 9/5

A(10) = 7.8

Therefore, the tenth term of the arithmetic sequence is 7.8.

Answers

Did you ever get the answer?

I did mine but i don’t know if it’s correct (I haven’t submitted it yet)

Area = 1/2 * base * height

Base= b = 20

Height = BD = 9.05

Area = 1/2 * 20 * 9.05

Area = 90.5 units squared

The expression for the area of ΔABC will be A = 1/2 x CA x BD, and the area is 90.5 square units.

What is the area of the triangle?

The area of the triangle is given as

A = 1/2 x B x H

Where B is the base and H is the height of the triangle.

Then the expression for the area of ΔABC will be

A = 1/2 x CA x BD

A = 1/2 x 20 x 9.05

A = 90.5 square units

Lin solved the equation 8( x - 3 ) + 7 = 2x( 4 - 17 ) incorrectly.
Find the errors in her solution. What should her answer have been?

Lin's solution:

8( x - 3 ) + 7 = 2x( 4 - 17 )

8( x - 3 ) + 7 = 2x(13 )

8x - 24 + 7 = 26x

8x - 17 = 26x

-17 = 34x

-½ = x

Answers

Let’s do the equation ourselves

8( x - 3 ) + 7 = 2x( 4 - 17 )

Let’s condense as she did

8( x - 3 ) + 7 = 2x ( -13 )

Distribute

8x - 24 + 7 = -26x

Combine like terms

8x - 17 = -26x

Move x to one side

-17 = -34x

Divide by -34

1/2 = x

Lin had subtracted 4 - 17 incorrectly, having the number 13 as a positive instead of a negative number. Her answer should have been 1/2 instead of -1/2.
