Answer:

314 m²

Step-by-step explanation:

the surface area of a sphere (As) is

As = 4×pi×r²

our radius r (half of the diameter) here is 5m.

As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²

What is −3/8÷7/12 ?
RSB [31]

Answer:

-9/14

Step-by-step explanation:

This is my simplest-

Do the keep-change-flip method for this problem (and also any problem involving this)

KEEP -3/8

CHANGE the division sign to multiplication

FLIP the last fraction. 7/12 to 12/7

Now solve the problem by multiplying the fractions

-3/8 × 12/7 =

-3 × 12 = -36

8 × 7 = 56

-36 / 56 =

Simplify it by dividing the numerator (up of the line) and denominator (below the line) to get -9/14

Step-by-step explanation:

so it will be 3,0261
