Answer:

Approximate surface area of the sphere is:

50.24 cm²

Step-by-step explanation:

We know that:

Surface area of sphere is given by 4πr²

Where r is the radius of the sphere

Here r=2 cm

Surface area=4×3.14×2²

                    = 50.24 cm²

Hence, approximate surface area of the sphere is:

50.24 cm²

Marrrta [24]

Answer:

law of cosines states c^2=a^2+b^2-2abc

b^2=26^2+24^2-2(26×24)cos 134°

b^2=676+576-1248cos134°

cos134= -0.6946

b^2=1252-12(-0.6946)

12×(-0.6946)= -8.3352

b^2=1252-(-8.3352)

b^2=1252+8.3352

b^2=1260.33

b=√1260.33

b=35.50

4 7/8 X 2= <br> can someone explain how to work this out?
Ahat [919]
To answer this, first multiply 7/8 by 2. To do that, multiply the numerator, 7, by 2 to get 14, which is 14/8. This is an improper fraction, and simplified it is 1 6/8. That is also equal to 1 3/4. Then multiply 4 by 2 to get 8 and add that to 1 3/4 to get your final answer: 9 3/4. Hope this helps!

how do you get the answer for 1 5 over 8 and decimal 1.625 PLZ HELP I WILL GIVE YOU 50 POINTS FOR THIS
frutty [35]
1.625 as a fraction is 1 5/8

15/8 simplified is 1 7/8

if you are using the word "and" to represent multiplication here you go:

first i would change both fractions to a mixed number

13/8×15/8=195/64
simplify

your answer would be 3 3/64

if you are using "and" to represent adding here you go:

1.625 as a fraction is 1 5/8

first i would change 1 5/8 to a mixed number:  13/8

so then add 15/8+13/8=28/8

simplify:  
28÷4=7
8÷4=2

7/2=3 1/2
  
i hope this helped
