Answer:

Step-by-step explanation:

A basketball is basically a sphere, so it suffices to calculate the surface are of the ball to determine the amount of required material. Given a sphere of radius r we have that the surface area is 4\pi r^2

In this case, r = 11.14 cm. So the area is aproximately 1159.48 squared cm. (1159.48 = 4\pi (11.14)^2)

How to solve 11×11-6×17+4
almond37 [142]

use the order of operations for this equation.

multiplication comes first.

11(11) - 6(17) + 4

121 - 102 + 4

for addition and subtraction, order doesn’t matter.

121 - 102 = 19

19 + 4 = 23

answer = 23

Solve the equation for x. show your work log(2x-6)=2
borishaifa [10]

Answer:

x = e^2/2 + 3

Step-by-step explanation:

Solve for x:

log(2 x - 6) = 2

Hint: | Eliminate the logarithm from the left hand side.

Cancel logarithms by taking exp of both sides:

2 x - 6 = e^2

Hint: | Isolate terms with x to the left hand side.

Add 6 to both sides:

2 x = e^2 + 6

Hint: | Solve for x.

Divide both sides by 2:

Answer: x = e^2/2 + 3

Janelle has a 12-ounce can of soft drink. She drinks 3/5 of the soft drink.
guapka [62]

Answer:

Answer:  4.8 ounces

Step-by-step explanation:

In total there are 12 ounces. If she drinks 3/5 of 12 you multiply 3/5 by 12.

3/5 * 12 would be equal to 3/5 * 12/1 which is 36/5. You have found how much she has drank. 36/5 is also equal to 7.2 ounces. Subtract 7.2 form 12 and you get 4.8 ounces.

Hope this helped!

Val walks 2 3 fifths miles each day. Bill runs 10 miles once every 4 days. In four days, who covers the greater distance?
melisa1 [442]
Val covers greater distance because 2 3/5 x 4 = 10 2/5. Bill only ran 10 miles so Val covered 2/5 more miles than him.
