Answer:

radius \: of \: earth \:  = 6.4 \times  {10}^{6} \: m  \\ volume  \: of \: a \: sphere =  \frac{4}{3} \pi {r}^{3}  \\  =  \frac{4}{3}  \times 3.14 \times (6.4 \times  {10}^{6} ) ^{3}  \\  = 1.098 \times  {10}^{21}  \:  {m}^{3}  \\ or \\  = 1.098 \times  {10}^{12}  \:  {km}^{3}

Evaluate each expression using the values m = 7, r = 8, and t = 2.
user100 [1]

So I'll walk through the first 2. Then please try the other ones and let me know if you run into more problems.

5m-6

If m is equal to 7, then replace m with 7.

5(7)-6

5x7=35 so the expression is now 35-6. Solve.

35-6=29

So that was the first one.

4m+t

We just do what we do with the first problem.

4(7)+(2)

4x7=28 so the expression is 28+2.

28+2=28

---

hope it helps

p.s. When there is subtraction, add. When there is division, multiply to cancel that out. When there is multiplication, divide to cancel. etc.
