Step-by-step explanation:

if you take the diameter of a circle and put it around the circumference you will need to have 3 and a bit more (pi=3.14) of diameters to cover the whole circumference.

C = pi*d = 3.14 * 7 = 21.98 feet

Answer:

Yes

Answer:

C=9.42

Step-by-step explanation:

Formulas: C=2πr or C=πd

Were gonna use C=2πr

"r"stands for radius from the problem we know that the radius is 1.5 .

Now we substitute the "r" for 1.5, it looks like this C=2π1.5 .

Now we multiply 2x1.5=3 . Now you are left with C=3π

Now you need to multiply 3xπ (Instead of π use 3.14) it would look like this 3x3.14= 9.42

Answer:

12.62

Step-by-step explanation:

imagine a circle with the center at the corner (let's call it A) with the 31 degree angle. the radius is AB.

so,

x = sin(31)×AB

and

21 = cos(31)×AB

therefore,

AB = 21/cos(31) = 24.4993...

=> x = sin(31)×24.4993... = 12.62 (12.61807...)

A)butter= 12

sugar  = 9.6

syrup= 4.8

eggs= 2.4

A ratio indicates how many times one number contains another.

Given:

5:4:2:1

Let the common ratio be x

So, butter= 5x

sugar= 4x

syrup = 2x

egg= x

As, eggs= 2.4 kg

So, x= 2.4

Now,

butter= 5x = 5* 2.4 = 12

sugar= 4x = 4* 2.4 = 9.6

syrup = 2x  = 2* 2.4 = 4.8

Answer:

614

Step-by-step explanation:

15 x 13 = 195    two times   195 x 2 = 390

4 x 15 = 60    two times   60 x 2 = 120

4 x 13 = 52      two times   52 x 2 = 104

104 + 120 + 390 = 614

Answer:

SA = 2(l·w)+2(w·h)+2(l·h)

SA = 614 sq in

Step-by-step explanation:

SA = 2(4x13)+2(13x15)+2(4x15)

= 2(52)+2(195)+2(60)

= 104 + 390 + 120

= 614

Answer:

Area of remaining plastic = 36.55 cm² (Approx.)

Step-by-step explanation:

Given:

Diameter of plastic dial of telephone = 8 cm

Diameter of middle hole = 4 cm

Diameter of ten small holes = 1.2 cm

Find:

Area of remaining plastic

Computation;

Radius of plastic dial of telephone = 8/2 = 4 cm

Radius of middle hole = 4/2 = 2 cm

Radius of ten small holes = 1.2/2 = 0.6 cm

Area of remaining plastic = Area of plastic dial - Area of middle hole - 10[Area of small holes]

Area of remaining plastic = π(4)² - π(2)² - π(0.6)²

Area of remaining plastic = π(16) - π(4) - π(0.36)

Area of remaining plastic = π[16 - 4 - 0.36]

Area of remaining plastic = π[11.64]

Area of remaining plastic = (3.14)(11.64)

Area of remaining plastic = 36.5496

Area of remaining plastic = 36.55 cm² (Approx.)

Answer:

The enrollment after 5 years is 10,724

Step-by-step explanation:

Generally, we can have the depreciation formula written as follows;

A = P(1 - r)^t

A is the number of enrollment in after a certain number of years t

P is the initial population which is 13,500

r is the rate of depreciation which is 4.5% = 4.5/100 = 0.045

t = 5 years

Substituting these values, we have it that;

A = 13,500(1-0.045)^5

A = 10,723.84

Answer:141.3

Step-by-step explanation:

The volume would be the Cone + Cylinder. So, use 1/3 x pi x r^2 x h and since the height is 6-3=3, you get 9 x 3.14 x 6 x 1/3 which is 56.52. The volume of the cylinder is pi x r^2 x h, which is 9 x 3.14 x 3, is 84.78. Now, add 56.52+84.78 = 141.3. Hope this helps

Answer:

Step-by-step explanation:

you actually dont have to do any division in this problem. since you know the area of the square and its depth, you simply multiply to two fractions, so [tex]\frac{25}{4} *\frac{8}{5}[/tex] when you multiply fractions all you do is multiply the tops and and bottoms, so 25 * 8=200 and 5 * 4=20, so the fraction is now 200/20, so when divide both sides by 20, the answer is 10. another way to demonstrate this in case you didnt understand is that you can rewrite your equation as [tex]\frac{25 * 8}{4 * 5}[/tex] then all you have to do is perform the opperation.

The formula to calculate arc length when central angle is in degrees =

Arc length = θ/360 × 2πr

r = radius = 1

θ = 81°

Hence:

Arc length in π =

= 162π/360

= 9π/20

Therefore, the arc length = 9π/20

Option B is the correct option

Answer:

bounce 1

Step-by-step explanation:

Answer:

the smaller square length is 3cm

the larger square length is 6cm

hence their ratio will be 3:6

Simplify the ratio

we have our final answer to be 1:2

The required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Side of smaller square, a = 3
Side of the larger square, b = 6

According to the question,

The ratio of the side length of the smaller square to the side length of the larger square,

= a / b = 3 / 6
= 1 / 2

Thus, the required ratio of the side length of the smaller square to the side length of the larger square is 1 : 2.
