To find the area of the wrapping paper you have to find the serface area of the ball 
you have the volume so you have to find the raduis using the formula
r=3(v/4pi)^1/3
r=3(288pi/4pi)^1/3
r=3(72)^1/3
r=216^1/3
r=6
then the surface area of the sphere
SA=4pi x r^2
SA=4pi x 6^2
SA=4pi x 36
SA=144pi

Answer:

No. of boxes = 10

Oranges per box = 56

Total no. of oranges = 56*10=560

No. of bad oranges = 560/40= 14

(i) Probability of bad orange = 14/560 = 1/40

(ii) no of oranges expected to be bad = 14 ( found above)

Hope it helps.............. :)

In △EKL, m∠K = 90º, m∠E = 25º, EK = 3 cm, KH - altitude. Find EH.
laiz [17]

Answer:

EH = 3.31

Step-by-step explanation:

We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.

Where,

EK = Base = 3

KH = perpendicular altitude

EH = Hypotenuse

m<K = 90

m<E = 25

We know that

cosθ = Base/ Hypotenuse

cos 25 = 3/ EH

EH = 3/cos25

EH = 3.31

Perpendicular alitutude can also be calculated by using the formula for tanθ.

andrew-mc [135]
Divide 5 1/2, or 11/2 by 3/4. You can do that by multiplying 11/2 and 4/3 to get 44/6. Simplify and you get 22/3, which is about 7.33 or 7 1/3. If he can only paint whole dog houses, the answer is 7.

What is the measure of angles 1, 2, and 3?​
stellarik [79]

Answer:

1=  70

2= 65

3=  95

For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)
