The lateral area of the prism is given by:
LA=[area of the two triangles]+[area of the lateral rectangles]
hypotenuse of the triangle will be given by Pythagorean:
c^2=a^2+b^2
c^2=6^2+4^2
c^2=52
c=sqrt52
c=7.211'
thus the lateral area will be:
L.A=2[1/2*4*6]+[6*8]+[8*7.211]
L.A=24+48+57.69
L.A=129.69 in^2
The total are will be given by:
T.A=L.A+base area
base area=length*width
=4*8
=32 in^2
thus;
T.A=32+129.69
T.A=161.69 in^2
Answer:
The unknown number is 2/15.
Step-by-step explanation:
4/5+x=14/15
x=14/15-4/5
x=14/15-12/15
x=2/15
Answer:

Step-by-step explanation:
Answer:
x=-2
Step-by-step explanation:
Since it is an equilateral triangle (note the little lines across the legs of corner 2) the other angle must be 69° as well.
That leaves 180-69-69 = 42 for ∠2.
So x + 44 = 42 => x = 42-44 = -2.
Answer:
the answer is d!
Step-by-step explanation:
because the radius is measuring the distance from any point on the circle to the very center of the circle
