A circle circumference is approximately 76 cm. estimate the radius diameter and area of the circle

1 answer:

6 0

The circumference of a circle is C = 2πr^2 (2nd power) Radius (r) is the distance from the center of the circle to the outside of it. To find radius divide the diameter (d) by 2. The diameter (d) of a circle is the radius (r) multiplied by 2. To find the diameter (d) you need to do C ÷ π.

For example):
Finding diameter - 76/3.14 = 24.19 (d)

Finding radius - 24.19/2 = 12.095 (r)

EDIT: (C) Means Circumference

The value of ac is 36 and the value of b is 13. Then the value of ac + b is 49. The two numbers are 4 and 9.

<h3>What is polynomial?</h3>

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Consider the trinomial 6x² + 13x + 6.

Compare with the standard equation, we have

ax² + bx + c

Then we have

a = 6

b = 13

c = 6

The product of ac will be

ac = 6 × 6 = 36

The sum of ac and b will be

ac + b = 36 + 13 = 49

The two numbers that have a product of ac and a sum of b are 4 and 9.

Use each method to solve system of linear equation. Show your solution.

Sphinxa [80]

Answer:

x=-1 y =-1

Step-by-step explanation:

multiply equation 1 with (-2)

+6x-2y=-14

5x+2y=3

now add equation 1 to equation 2

11x=-11

x=-1

now substitute x=1 in 1 or 2

5(1)+2y=3 5+2y=3 2y=3-5 2y= -2 y= -1
