In a cave a stalactite get 4 milimeters longer each year this years it is 72 centimeters long. How many years until it is 1 meter long?

Answer:

B. 9

Step-by-step explanation:

the area = π × 3² = 9π ft²

Area of a circle = pi x R^2

R is the radius which is 1/2 the diameter.

R = 6/2 = 3 feet

Area = pi x3^2

Area = 9pi

The answer is B

Answer:

312 inches

Step-by-step explanation:

Surface Area = 2×(8×12 + 8×3 + 12×3) = 312 inches

Answer:

312

(12x3)x2=72

(12x8)x2=192

(8x3)x2=48

72+192+48=312

Answer:

The length of side EF is 10 units.

If there is any specific measurement for each unit, multiply 10 by the measurement amount.

Answer:

10 units

Step-by-step explanation:

The side of EF is 10 units

The side of DE is 10 units

The side of DF is about 14.1 units

Answer:

Half of 3 is 1.5(new radius)

1.5^2 = 2.25

2.25 x 3.14 = 7.065

7.065 x 2 = 14.13(area of two circles)

2 x 3.14 x 1.5 = 9.42

9.42(circumference)  x 4(height) = 37.68(area of lateral)

Add the given areas:

37.68 + 14.13 = 51.81 cm2 is your answer.

Answer:

66 pots

Step-by-step explanation:

The height of flower pot is 66 inches

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Measurement of mug = 6 inches

as, the slower pot is 11 times taller than the mug

=11 * 6

=66 inches.

Hence, the height of flower pot is 66 inches

Answer:

the unknown number of fish is 26

Step-by-step explanation:

I figured this out by subtracting 68 - 47 = x.

x = 26

Answer:

Unknow fishes = 26

Step-by-step explanation:

We are given that 42 and x fishes sum up to 68 fishes, so we can say;

42 + x = 68

x = 68 - 42

x = 26

Therefore the number of unknown fishes = 26

Answer:  4.3 cm

Step-by-step explanation:

Leroy's rectangle's width is 7.6 cm in length and the length of the triangle is 11.9 cm.

The length is therefore longer than the width and the difference is:

= Length - Width

= 11.9 - 7.6

= 4.3 cm

Answer:

The Pythagoras theorem has three places namely; hypotenus, adjacent, and opposite

Answer:

Step-by-step explanation:

Pythagorean theorem will be applied to right triangles. The formula is a^2+b^2=c^2 where a and b represent the legs of the truss de c is the hypotenuse. Now let’s say I had a leg that was 4 inches and a second leg that was 8 inches. I would then have to try and find the hypotenuse. So plug it into the equation

4^2+8^2=c^2

Now 4 to the power of 2 is 16 and 8 is 64

16+64=c (note we got ride of the ^2 for the c)

So 80=c

Now what we want to do is take the square root of 80 since our c needs to be rooted. So the square root of 80 would be your answer.

Answer:

24km²

Step-by-step explanation:

12-4 is 8 and if you visualize the triangle being put on top of the other triangle it makes a complete rectangle in which you multiple 8 time 3 to get 24 km²

Answer:

24 km²

Step-by-step explanation:

12 - 4 = 8

8 ÷ 2 = 4

4 · 3 = 12

12 ÷ 2 = 6

4 · 3 = 12

6 km² + 12 km² + 6 km²

24 km²

Step-by-step explanation:

radius of circle= 18.2÷2

=9.1

area of circle= πr²

= 3.14×9.1²

= 260.02 cm² (nearest hundredth)

Answer:

Solution given:

diameter=18.2cm

[r]radius=diameter /2=18.2/2=9.1cm

Now

Area of circle=πr²=3.14*(9.1)²=260.02cm²

The area is _260__ square cm.
