Answer:
Step-by-step explanation:
Lateral surface area of the triangular prism = Perimeter of the triangular base × Height
By applying Pythagoras theorem in ΔABC,
AC² = AB² + BC²
(34)² = (16)² + BC²
BC =
=
= 30 in.
Perimeter of the triangular base = AB + BC + AC
= 16 + 30 + 34
= 80 in
Lateral surface area = 80 × 22
= 1760 in²
Total Surface area = Lateral surface area + 2(Surface area of the triangular base)
Surface area of the triangular base =
=
= 240 in²
Total surface area = 1760 + 2(240)
= 1760 + 480
= 2240 in²
Volume = Area of the triangular base × Height
= 240 × 20
= 4800 in³
Answer:D
Step-by-step explanation:
Answer:
Uhh, I think the answer is <em>b</em>?
Step-by-step explanation:
if you look at the area <em>d</em>, it's kind of the same as 18 mm but it isn't. It's a few inches off the same inch as 18 mm, so it MIGHT be <em>b</em>.
(I MIGHT BE WRONG, IF I AM, I AM SORRY. I'M NOT THAT SMART, SO EXPECT SOME WRONG ANSWERS OR NOT.)
The answer is x-5 First collect like term so it will be x-9+4 and then subtract 9-4= 5 so now it will be x-5
