Answer:
1306.24 cm².
Step-by-step explanation:
From the diagram given above, we obtained the following information:
Radius (r) = 13 cm
Pi (π) = 3.14
Slant height (l) = 19 cm
Surface Area (SA) =.?
The surface area of the cone can be obtained as follow:
SA = πr² + πrl
SA = πr ( r + l)
SA = 3.14 × 13 ( 13 + 19)
SA = 40.82 (32)
SA= 1306.24 cm²
Therefore, the surface area of the cone is 1306.24 cm².
The ways we can prove the triangles congruent:
SAS (side, angle, side)
ASA (angle, side, angle)
AAS (angle, angle, side)
SSS (all sides equal)
RHS/HL (Right Angle-Hypotenuse-Side/Hypotenuse-legs)
In these cases:
A. <B = <E
<A = <D
AC=DF
AAS (angle, angle, side) could be used.
B. AB=ED
BC=EF
AC=DF
SSS (all sides equal) could be used.
C.<BEA=<CED (right opposite angles)
As there is only one pair of equal angles we can find,there is not enough information.
D.<B = <E
BC=CE
<ECD < ACE(right opposite angles)
ASA (angle, side, angle) could be used.
Hope it helps!
Answer:
There are 18 odd numbers
Step-by-step explanation:
1,3,5,7,9,11,13,15,17, 19,21,23, 25,27,29,31,33,35
You will need to deposit $ 10,957 each year until retirement to achieve your retirement goals.
<h3>What is compound interest, and how does it work?</h3>
Compound interest is computed on a loan or deposit based on the starting principle and the preceding period's accrued interest.
Principal(P)=$40,000
(Time period)T=25+15 = 40 year
R=8%
The final balance is $273,938.99 and the total compound interest is $233,938.99.
The amount he has to deposit each year is found as;
⇒$273,938.99/25
⇒ $ 10,957
Hence. you will need to deposit $ 10,957 each year until retirement to achieve your retirement goals.
