Answer:

751.124

Step-by-step explanation:

area of a cricle is

πr^2

take π to be 22÷7

A= πr^2

A=22÷7*15*15

A=22÷7*225

7 divides 225

= 34.142

22*34.142

A= 751.124

Someone help me

Aneli [31]

Answer:

see the explanation

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$

where

D is the diameter

In this problem we have

$C=2.88\ in$

$\pi=3$

substitute and solve for D

$2.88=(3)D$

$D=2.88/3$

$D=0.96\ in$

we know that

The length of the row of quarters is equal to multiply the diameter of the quarter by the number of quarters in the row

For 4 quarters in the row, the length is equal to --> $0.96(3)=3.84\ in$

For 6 quarters in the row, the length is equal to --> $0.96(6)=5.76\ in$

For 12 quarters in the row, the length is equal to -> $0.96(12)=11.52\ in$

How do you solve 3x^6- 39x^4+ 108x^2= 0

ArbitrLikvidat [17]

You can first take out an x^2 from each number , 3x^6 - 39x^4 + 108x^2 = x^2 ( 3x^4 - 39x^2 + 108) Then just factor and solve for the zero's of the equation
