Answer:
![SA=784\pi\ units^{2}](https://tex.z-dn.net/?f=SA%3D784%5Cpi%5C%20units%5E%7B2%7D)
Step-by-step explanation:
we know that
The surface area of a sphere is equal to
![SA=4\pi r^{2}](https://tex.z-dn.net/?f=SA%3D4%5Cpi%20r%5E%7B2%7D)
we have
![r=14\ units](https://tex.z-dn.net/?f=r%3D14%5C%20units)
substitute
![SA=4\pi (14)^{2}](https://tex.z-dn.net/?f=SA%3D4%5Cpi%20%2814%29%5E%7B2%7D)
![SA=784\pi\ units^{2}](https://tex.z-dn.net/?f=SA%3D784%5Cpi%5C%20units%5E%7B2%7D)
Answer:
180 m²
Step-by-step explanation:
Surface area = 2 ( lw + wh + lh)
= 2( 6x3 + 3x8+8x6)
= 180 m²
Answer:
The population of bacteria is increasing.
Step-by-step explanation:
The function modelling the population of bacteria in the given culture is an exponential function; We have a base 1.03 and an exponent t. An exponential function is said to be increasing if the base is strictly greater than 1, this implies that the population of the bacteria is increasing as t increases from 0 to infinity.
