Answer:
1176.5 square feet
Step-by-step explanation:
<em>Let us recall from the following question,</em>
<em>Because fuel tank is a cylinder, the first step to take is get the surface area of this cylinder.</em>
<em>The Surface area of a cylinder = 2. π. r. 2. +. 2. π.</em>
<em>Then,</em>
<em>The given values (h = 50, r = 7/2 = 3.5) as applied from the formula given,</em>
<em>The area Surface a of fuel tank = 1176.5 square feet</em>
P= L+L+L+L
P= 122+25+122+25
P= 294 inches *square sigh*
Weight of each rock is 14.8 ounces.
Step-by-step explanation:
Given,
Total number of rocks = 10
6 rocks weigh 10 ounce each
4 rocks weigh 22 ounce each.
To find the the weight of each rock.
Now,
Weight of 6 rocks = 10×6 ounces = 60 ounces
Weight of 4 rocks = 22×4 ounces = 88 ounces
So,
Weight of 10 rocks = 88+60 = 148 ounces
Hence,
Weight of each rock = 148÷10 = 14.8 ounces.
