Answer:
can you please identify the crossed out ones?
3-4/.8=1.25
then use the probability z chart to get
10.56%
Answer:
No, I got 18
Step-by-step explanation:
180-78=102
180-11-49=120
180-120=60
x=180-102-60=18
Surface area is defined as the sum of all the areas covers the object so here we have 2 cylinders and the
Area of a cylinder = side area + area of the circle
side area = <span>perimeter * height = 2*pi* r *h
</span>area of the circle = pi * r^2
for the cylinder, we have 2 area circle and 1 side area
so surface area = 2 *pi * r*h + 2 pi* r^2
so for the first cylinder
A1 = 2*pi*r*h +2 pi * r^2 = (2*pi * 2 *2) +( 2 *pi * 2^2 ) = 16pi inch^2
A2 = 2*pi*r*h + 2pi *r^2 = ( 2 * pi * 1.25*3)+( 2*pi *(1.25)^2) = 85/8 pi inch^2
A= A1 +A2
A = 16pi + 85/8 pi = 83.645 inch^2
