Answer:
SA: 456
V: 408
Step-by-step explanation:
To find the volume of this prism, you first need to find the area of the triangular base. The base has dimensions 6 by 8, and since it's a triangle, the area of the base is 6*8/2=24. Multiplying this by the length of the prism, you get a volume of 24*17=408. For the surface area, you need to find and add together the areas of all of the surfaces. We have already determined that the area of the two triangular bases are 24. The rectangle formed by the leg with length 6 has area 6*17=102, the one with length 8 has area 136, and the hypotenuse has area 170. Adding all of this together, you get a surface area of 24+24+102+136+170=456 square centimeters. Hope this helps!
Answer:
Step-by-step explanation:
ollowing is the formula for calculating compound interest when time period is specified in years and interest rate in % per annum.
A = P(1+r/n)nt
CI = A-P
Where,
CI = Compounded interest
A = Final amount
P = Principal
t = Time period in years
n = Number of compounding periods per year
r = Interest rate
Calculation Examples
You can solve for any variable by rearranging the compound interest formula as illustrated in the following examples:-
1. What is the compound interest of 75000 at 7.9% per annum compounded semi-annually in 3 years?
Ans. A = P(1+r/n)nt = 75000(1 + (7.9 / 100) / 2)6 = 94625.51
Interest = 94625.51 - 75000 = 19625.51
Since the area of B is 9 times the area of A, we know that the sides of B are √9= 3 times the length of the sides of A.
That's how.
