Answer:
12 cm x 15 cm
Step-by-step explanation:
if the picture frame thickness is x,
then the frame dimension would be (8+2x) cm by (11+2x) cm
area is (8+2x)(11+2x)=180
solve for x, x= 2, -23/2
x is thickness, so should be >0, so x=2
frame dimension: 12 x 16
Answer:
x = 80
Step-by-step explanation:
In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360
115 + 95 + 70 + x = 360 just add the like terms
280 + x = 360 now subtract 280 from both sides so x is alone and you can figure out its value
x= 80
Answer:
284.837734 ft^3 rounded up to 284.84 ft^3
Step-by-step explanation:
Cylinder Volume: pi*r^2h
pi*4^2*4=201.06193
Cone Volume: pi*r^2*(h/3)
pi*4^2*(5/3)=83.7758041
201.06193+83.7758041=284.837734
284.837734 ft^3
