C)
2/4
2 is half of 4
2 are shaded in out of 4
Answer:
3.14 km
Step-by-step explanation:
we know that area of a circle is πr², where r is the radius
if here radius is 1 kilometres, π is 3.14
then, circle's area = 3.14 * 1 * 1 = 3.14 km
Answer:
Step-by-step explanation:
Expected growth = 0.15*85 + 0.20 *20 + 0.45*10+0.20 * -20
= 17.25%.
Here we have a right triangle with hypotenuse h, which is to be found. The top of the ladder is 30 feet above the ground, and that distance is opposite the 42 degree angle mentioned. Use the sine function to determine the hypotenuse, h:
sin 42 deg = opp / hyp, or hyp*sin 42 deg = 30 ft. Then hyp = (30 ft)(sin 42), which in turn equals hyp = (30 ft) / (0.669) = 44.8 feet (answer)
Your answer is gonna be -4/3 !!
