Area of a circle formula = $\pi$ r² where r means radius and $\pi$ means 3.14

3.14(9)^2 = 254.34 = area

Circumference formula: 2 $\pi$ r

2(3.14)(9) = 56.52 = circumference

If I have 5 pears in one box and 2 pears in another box. <br> How many pears do I have altogether?

nalin [4]

Answer:

7, or 5

Step-by-step explanation:

If the pears are in separate boxes, then 7

If one box is inside the other box, then 5, as 2 pears would be inside the inner box, and 3 pears would be in the outer box. 5 pears total would be in the outer box (including the ones from the inner box)

Steve is analyzing two linear functions, f(x) and g(x). Will they intersect?

user100 [1]

We get for x=2, f(2)=3, (f(x)=x+1) and g(2)=3, that means that they intersect at the moint M(3,3), so the answer is
(a)Yes, at a point with a positive x-coordinate

I need help thank you!<br> (7x + 14)<br> (15x - 4)

sergey [27]

Answer:

(7x + 14)° = 84°

(15x - 4)° = 146°

Step-by-step explanation:

62° + (7x + 14)° = (15x - 4)°

62° +7x + 14 = 15x - 4

15x - 7x = 62 + 14 + 4

8x = 80
