Answer 1

Answer:

Question

Find the total surface area of a container in cylindrical shape whose diameter is 28 cm and height is 15 cm.

Answer

Solution, Given, diameter = 28 cm, so radius = 28/2 = 14 cm

and height = 15 cm

By the formula of total surface are, we know;

TSA = 2πr (h + r) = 2x 22/7 x 14 x (15 + 14)

TSA = 2 x 22 x 2 x 29

TSA = 2552 sq.cm

Hence, the total surface area of container is 2552 sq.cm.

Answer 2

Question:-

$\sqrt{-2+2i√3}$ + $\sqrt{-2-2i√3}$ = $2$

Find:-

the total surface area of a container in cylindrical shape whose diameter is 28 cm and height is 15 cm.

Solution:-

$diameter = 28cm$

$radius = 28 \div 2 = 14 \: cm$

$height = 15 \: cm$

Given:-

$TSA = 2\pi \: r(h + r) = 2x \: 22 \div 7 \times 14 \times (15 + 14)$

$TSA = 2 \times 22 \times 2 \times 29$

$TSA = 2552 \: sq. \: cm$

Answer:-

$TSA = 2552$

Full form:-

TSA= Transportation Security Administration

Define TSA:-

It oversees contracts that are held by private screening firms who serve in a similar capacity.The TSA manages security policies for railroads, buses, pipelines, ports, mass transit systems and highways.The results of the tests showed that the TSA screeners failed to detect weapons, drugs, and explosives almost 80 percent of the time. Also, you may not work as TSA agent if you are not a US citizen.
