Answer:

Volume = 11488.21

Area = 2461.76

Step-by-step explanation:

Given

Radius, r = 14\ in

Shape: Sphere

Solving (a): The Volume

This is calculated as:

Volume = \frac{4}{3}\pi r^3

Take \pi as 3.14 and substitute 14 for r

Volume = \frac{4}{3} * 3.14 * 14^3

Volume = \frac{4}{3} * 3.14 * 2744

Volume = \frac{4 * 3.14 * 2744}{3}

Volume = \frac{34464.64}{3}

Volume = 11488.21

Solving (b): The Surface Area

This is calculated as follows:

Area = 4\pi r^2

Take \pi as 3.14 and substitute 14 for r

Area = 4 * 3.14 * 14^2

Area = 4 * 3.14 * 196

Area = 2461.76

Someone please help me I suck @ simplifying thank you
dsp73

To solve this question, you would need to find the common denominator among the 2 fractions. In this case it would be

72.

Then multiply numbers to both of the fractions to get to the bottom number in both fractions equaling 72.

40/72 + 27/72 =67/72.

Try to reduce to lowest terms by dividing a common number from both of them if possible.

Where will these 2 lines intersect?<br><br> y = 2x + 7 and x = y + 4
defon
To find the intersecting point, you have to put the two formulas equal to each other
First isolate the same variable, in this case y
So y=x-4

Now we can say
2x + 7 = x - 4

Now solve for x

X= 3

Now fill this in in either one of the formulas

Y= 2 (3) + 7
Y= 13

So they’ll intersect at (3,13)
