Answer:
circumference: 37.7
area: 113.1
Step-by-step explanation:
for the future look up '___ of a circle'
and enter the radius (if u are given the diameter divide it by 2)
Answer:
<h3><u /></h3>
<u>Trigonometric identities</u>
<u />

Therefore, using the <u>identities</u>, the given expression can be <em>simplified</em> as follows:

A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b
(2(-2)+9(5)-5)-(6(-2)-4(5)+2)
(-4+45-5)-(-12-20+2)
(45-9)-(-32+2)
36+30
66
100•100 = 10,000
200•200 = 40,000
300•300 = 90,000
