Answer:

15.4 mm

Step-by-step explanation:

for semi circle is = (3.14× d )/2

for square = L + L + L +L

d = 6mm

L = 2mm

so

( 3.14 × 6)/2

+

2 × 3mm .. three sides only

= 15.4 mm

Answer:

area of circle having radius 3

is πr²=π*3²=9π square units

area of circle having radius 2

=πr²=π×2²=4π square units

again

area of big circle having radius [3+2]=5 units

=πr²=π×5²=25π square units

Now

area of shaded region=25π-4π-9π=12π or 37.7square units.

Answer:

12π units² or 37.7 units²

Step-by-step explanation:

Find the area of the 3 circles and subtract the areas of the two smallest ones.

Biggest circle area: π((3(2)+2(2))/2)² = π((6+4)/2)² = π(5²) = 25π units²

2nd Biggest circle area: π(3)² = 9π units²

Smallest circle area: π(2)² = 4π units²

Shaded area: 25π - (9π + 4π) = 25π - 13π = 12π units² or 37.7 units²

Answer:

16h^2-4h-42

Step-by-step explanation:

4h times 4h is 16h^2

4h times -7 is -28h

4h times 6 is 24h

6 times -7 is -42

Combine like terms to get 16h^2-4h-42

Explanation:

To solve for x, aka isolate it, you add 11 to both sides. Then you divide both sides by 2 like so:

[tex]2x-11 \ge 5\\\\2x \ge 5+11\\\\2x \ge 16\\\\x \ge \frac{16}{2}\\\\x \ge 8\\\\[/tex]

The inequality sign stays the same the entire time. It only flips if you divide both sides by a negative number, but that doesn't happen in this case.

Answer:

We have the surface area of the cylinder as 3,016.32 in^2

Step-by-step explanation:

What we have here is a cylinder of height 14 inches and diameter 32 inches

Mathematically we can calculate the surface area of a cylinder using the formula;

A = 2 * pi * r(r + h)

where r is diameter/2 = 32/2 = 16 inches

h = 14 inches

pi = 3.142

thus, we have it that;

A = 2 * 3.142 * 16(16 + 14)

A = 3016.32 in^2

The location of B is 0.2

Step-by-step explanation:

We have to be using decimals on each line except for the whole numbers. Since there are spaces/lines in between 0 and 1. It would go like 0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1. Then 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2. And so forth!

Answer:

115.15 cm²

Step-by-step explanation:

The area of a trapezoid = 1/2 (b1 + b2)h

Where:

b1 = first base = 8.2 cm

b2 = Second base = 15.3 cm

h = height = 9.8 cm

Hence, Area of the trapezoid =

1/2 (8.2 + 15.3) × 9.8

= 1/2 × (23.5) × 9.8

= 115.15 cm²

Therefore, the area, in square centimeters, of the trapezoid below is 115.15 cm²

Answer:

jack has 8 jellybeans and his brother has 17

Step-by-step explanation:

Jack have 8 jellies and his brother have 17 jellies.

A number expressed as a quotient, in which a numerator is divided by a denominator.

Total number of jellies= 25.

The jellies is to be divide between jack and his brother.

let us consider jack has 'x' jellies

Then, his brother have '2x+1'

So, x+ 2x+1=25

3x+1=25

3x=24

x=8

So, jack have 8 jellies and his brother have 2*8+1= 17 jellies.

Answer:

They are about 3.6 miles away from each other.

Step-by-step explanation:

2²+3² = C²

13=C²

√13 = C

C = 3.6

The distance between Josh and Ben is 3.6 miles

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.

According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that Josh and Ben spotted a bear in the woods while riding their bikes. Josh rode 3 miles north and Ben rode 2 miles east.

The formula of the Pythagorean theorem is given as,

C² = a² + b²

C² = 2²+3²

C² = 13

C = √13

C = 3.6

Therefore, the distance between Josh and Ben is 3.6 miles
