What is the area of a circle if the diameter is 16 millimetres

Mathematics
1 answer:
stiv31 [10]3 years ago
7 0

Answer:

201.1 mm²

Step-by-step explanation:

given that the diameter is 16mm,

radius = diameter ÷ 2 = 16÷2 = 8 mm

area of a circle is given by

A = πr², where

π=3.142

r = radius = 8 mm

Substituting these into the equation,

A = πr²

= 3.142 (8)²

= 201.088 mm²

= 201.1 mm² (rounded to nearest tenth)

Using the picture above what is the arc length of AB to the nearest hundredths?
qaws [65]

Answer:

Length of arc AB = 1.57 yds

Step-by-step explanation:

Given:

Central angle (θ) = 30°

Radius (r) = 3 yds

Required:

Length of arc AB approximated to the nearest hundredths

Solution:

Length of arc = θ/360 * 2πr

Length of arc AB = 30/360*2*π*3

Length of arc AB = 1.57079633

Length of arc AB = 1.57 yds (nearest hundredths)

Not sure how to do #69, it's a calc 1 question
Gnoma [55]
Let A( t , f( t ) ) be the point(s) at which the graph of the function has a horizontal tangent => f ' ( t ) = 0.

But, f ' ( x ) = [ ( x^2 ) ' * ( x - 1 ) - ( x^2 ) * ( x - 1 )' ] / ( x - 1 )^2 =>
f ' ( x ) = [ 2x( x - 1 ) - ( x^2 ) * 1 ] / ( x - 1 )^2 => f ' ( x ) = ( x^2 - 2x ) / ( x - 1 )^2;

f ' ( t ) = 0 <=> t^2 - 2t = 0 <=> t * ( t - 2 ) = 0 <=> t = 0 or t = 2 => f ( 0 ) = 0; f ( 2 ) = 4 => A 1 ( 0 , 0 ) and A 2 ( 2 , 4 ).

Given the function f(x)=4|x-5|+3 for what values of x is f(x)=15
Andreyy89

Answer:

  {2, 8}

Step-by-step explanation:

We want to find x for ...

  15 = 4|x -5| +3

  12 = 4|x -5| . . . . subtract 3

  3 = |x -5| . . . . . . divide by 4

  ±3 = x -5 . . . . . . show the meaning of absolute value

  5 ±3 = x = {2, 8} . . . . . add 5

The values of x for which f(x) = 15 are 2 and 8.
