Step-by-step explanation:
//I take it you're trying to find the area or circumference of a circle, so I'll do both.


= area
3.14 * <span>

= 28.26 (2 d.p)
</span>2

r = circumfrence
<span>2 * 3.14 * 3 = 18.84 (2 d.p)</span>
Answer:
6y²+40y--27
Step-by-step explanation:
(3y – 4) (2y + 7) + 1ly – 9
6y² + 21y -- 8y --28 + 11y --9
6y²+40y--27
4% =.04
20*.04= 0.8

Given,
hypotenuse = 23
adjacent = 4sqrt19
opposite = 15
then, using sohcahtoa,
sin m = 15/23 =0.652
cos m = 4sqrt19/23 = 0.758
tan m = 4sqrt19/15 = 1.162
