Explanation:
Divide the figure into areas for which you have a surface area formula. Use the appropriate formula for each area, then add up the results.
Formulas are available for surface areas of a cone, cylinder, sphere, pyramid, rectangular prism, and for plane shapes that are circles, ellipses, triangles, rectangles, trapezoids, and regular polygons.
Most of the figures for which you are asked to find the area will decompose to some subset of these shapes. Take care to identify the relevant dimensions of each of the constituent parts of the area, and to make sure that all parts are accounted for. Do not allow your parts of the area to overlap, unless you intend to account for that overlap by subtracting the area that is counted more than once.
Also, use your common sense. A semicircle will have half the area of a circle, for example.
In some cases, it may be expedient to compute the area of a larger figure than the one you have, then subtract the part of that area that is missing from your figure.
Answer:
0.079 would be the correct answer
Step-by-step explanation:
you just do 3/10 x 5/19 and then you get the answer
Answer:
540 miles
Step-by-step explanation:
60 times 9
A = deposit at US bank
b = deposit at 7/4 bank
c = deposit at Catch bank.
we know her total is 3886, thus a + b + c = 3886.
now, we know whatever "b" is, the amount at US bank, "a", is 3 times that much, thus a = 3b.
(3b) + b + c = 3886.
whatever% of anything, is just (whatever/100) * anything.
we know Catch bank gets 45% of whatever the sum of the other two is, well, US bank gets "3b", 7/4 bank gets "b", their total is 3b + b = 4b, and Catch bank gets 45% of that, (45/100) * 4b

how much is it for the Catch bank? well, (45/100) * 4(670).
It seems correct to me- i don’t see anything wrong so far
