Answer:

$256\pi {cm}^{2}$

Step-by-step explanation:

surface area of a sphere=4πr^2

diametre=16

$radius = \frac{diametre}{2}$

radius=8

$surface \: area \: of \: sphere = 4 \times \pi \times {8}^{2}$

$\: \: \: \: = 4 \times \pi \times 64$

$\: \: \: \: = 256\pi {cm}^{2}$

First, you have to simplify the equation:
y+3 = 3(x+5)
y+3=3x+15
So you multiply what’s inside the brackets (x+5) by the factor (3). So 3•x=3x, 3•5=15.
Then you rearrange the equation as necessary to convert it into standard form, which is Ax + By = C

DerKrebs [107]

Given that the original price of the model boat kit is $67.53 and he has a coupon of $25 off if a purchase is $50 or more. Since the purchase is more than $50, we will deduct 25 from 67.53 so the discounted price of the model boat kit would be $42.53. Hope this answers your question.
