Find the radius of the circle given the area of the sector is 153.9 and the angle measure

Mathematics
1 answer:
zloy xaker [14]2 years ago
3 0

Answer:

14

Step-by-step explanation:

area of sector = 153.9

or, (1/2) r²∅ = 153.9

or, r²∅ = 153.9 ×2

or, r²∅ = 307.8

or, r²× π/2 = 307.8

or, r² = 615.6/π

or, r² = 196

or, r=√196

r = 14

Set Question involving real and natural numbers
Allushta [10]

Only two real numbers satisfy x² = 23, so A is the set {-√23, √23}. B is the set of all non-negative real numbers. Then you can write the intersection in various ways, like

(i) A ∩ B = {√23} = {x ∈ R | x = √23} = {x ∈ R | x² = 23 and x > 0}

√23 is positive and so is already contained in B, so the union with A adds -√23 to the set B. Then

(ii) A U B = {-√23} U B = {x ∈ R | (x² = 23 and x < 0) or x ≥ 0}

A - B is the complement of B in A; that is, all elements of A not belonging to B. This means we remove √23 from A, so that

(iii) A - B = {-√23} = {x ∈ R | x² = 23 and x < 0}

I'm not entirely sure what you mean by "for µ = R" - possibly µ is used to mean "universal set"? If so, then

(iv.a) Aᶜ = {x ∈ R | x² ≠ 23} and Bᶜ = {x ∈ R | x < 0}.

N is a subset of B, so

(iv.b) N - B = N = {1, 2, 3, ...}

Eduardwww [97]

Evaluate the expression using x = –1 and y=3.

(6x^4y^3)

1. Substitute the values for the variables.

we plug in -1 for x  and 3 for y

(6x^4y^3)

(6(-1)^4(3)^3)

2. Identify grouping symbols, beginning with the innermost symbols.

(6*(-1)^4*(3)^3)

We take exponent and then we multiply

3. Determine and apply the rules of exponents to simplify

(6*(-1)^4*(3)^3)

(-1)^4 = -1 * -1 * -1 * -1 = 1

(3)^3 = 3*3*3= 27

(6*(1)*(27))

4. Evaluate.

(6*(1)*(27))

162

The value of the expression is 162
