<h3>
Answer: Choice D</h3>
====================================================
Explanation:
You'll have to go through each answer choice one by one to check if those dimensions lead to to a volume of roughly 9.5 m^3
For choice A, we have a radius of 0.7/2 = 0.35 meters and a height of 6.2 meters. The volume of the cylinder is pi*r^2*h = 3.14*(0.35)^2*6.2 = 2.38483 which rounds to 2.4 cubic meters. We can rule out choice A because we want 9.5 as a result instead of 2.4
We follow the same steps for choices B through D. You should find that choice D is the answer because:
V = pi*r^2*h = 3.14*(1.4/2)^2*6.2 = 9.53932 which rounds to 9.5 m^3.
Note the 1.4/2 is dividing the diameter 1.4 in half to get the radius.
The equation should be: y = -5x + 1
The circumference of a circle is pi times D. So, 94.2/pi = 29.98 or about 30 in
Answer:
A = 31.92 in^2
Step-by-step explanation:
Area of a triangle is 1/2(b*h)
So, you would take 1/2(5.4 * 4.8) + 1/2(7.9 * 4.8) which gives you 31.92
The answer is 2:1 because at first your ratio would be 18:9 but if you divide that by 9 (for simplifying purposes) than its 2:1
