If a circle has a circumference of C, what is the area of the circle in terms of C?

Answers

First you have to write down the formula on how to get the circumference of the circle (C = 2pi * Radius) and the Area of the circle which is (A=Pi*Radius^2). In getting the radius you need to transform the formula of the circumference by making the radius to be the unknown variable so it would become(R=C/2pi), after that you need to replace the radius in the formula of the area by the transformed formula of the circumference and you will come up of the formula of (A=Pi(C/2pi)^2).

Answer:

(-1)/7

1/(-7)

-(1/7)

These two equations will be equal to -1/7 as

(-1)/7=-1/7

1/(-7)=-1/7(THE SIGN OF THE DENOMINATOR WILL BE GIVEN TO THE NUMERATOR IF NEGATIVE)

-(1/7)=-1/7 (When we avoid the bracket the answer will be equalent)

Answer:

e= 2

W= 15

m= 9

Step-by-step explanation:

for e: yout multiply 5 x 7 to get 35 so 2 x 7 = 14

for W: 20/10 = 2 so divide 30/2 to get 15

for m: 11 x 2 = 22 so do 18 divided 2 to get 9

Answer:

E = 2

W = 15

M = 9

Step-by-step explanation:

You just have to make the denominator / numerator the same.

(E)/(5) = (14)/(35)

Multiply the first fraction by 7 so that their denominators are both 35.

(7E)/(35) = (14)/(35)

7E = 14

E = 14 ÷ 7

E = 2

(20)/(30) = (10)/(W)

Multiply the second fraction by 2 so that their numerators are both 20.

(20)/(30) = (20)/(2W)

2W = 30

W = 30 ÷ 2

W = 15

(M)/(11) = (18)/(22)

Multiply the first fraction by 2 so that their denominators are both 22.

(2M)/(22) = (18)/(22)

2M = 18

M = 18 ÷ 2

M = 9

A coin is tossed 40 times. Heads appeared 18 times. Find the experimental probability of landing on heads.

Answers

The experimental probability of landing on heads will be 9/20 or 0.45.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

A coin is tossed 40 times.

Heads appeared 18 times.

Total events = 40

Favorable events = 18

Then the experimental probability of landing on heads will be

P = 18 / 40

P = 9 / 20

P = 0.45

Answer:

Step-by-step explanation:

Tan Ф = opposite/adjacent = 170/90 = 1.89

Ф = tan⁻¹ 1.89 = 62.1°

tan Ф = x/207

tan 62.1° x 207 = x

1.89 x 207 = 391.23

Answer:

391 ft

Step-by-step explanation:

Using similar figures

X/170 = 207/90

X = 170 × 207/90

X = 391 ft

Solve for x. Round to the nearest tenth of a degree, if necessary.
