Diameter is twice the radius. A=πr^2.
First, solve for r:
32.15=πr^2
<em>*Divide both sides by </em>π*
10.2337=r^2
<em>*Take the square root of both sides*</em>
3.199=r
Multiply the radius by 2:
3.199*2=6.398
D. 6.4 feet
Hope this helps!!
Answer:
(-4,0) and (4,0)
Step-by-step explanation:
The x-intercepts occur for values of x where f(x) = 0.
f(x) = 0 when the nominator (
) = 0.
is a difference of squares,
so you can factor it as (x + 4)(x – 4)
When x = –4 or x = 4, the nominator is 0, and f(x) = 0
They are not similar. The angles are not equal
8x - 6 - 12x^2 + 9x
2(4x-3)-3x(3x-3)
=> (2-3x)(3x-3)
=> 3(x-1)(2-3x)
52 and 48 if you take away 2 from 50 then,add it to the other 50 52+48
