You can write it as 2x10x47 then 47x2 is equal to 94 and time it with 10 so it’s 940
Answer:
A
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius
here r = 2, hence
A = 4π × 2² = 4π × 4 = 16π units² → A
Answer:
21
Step-by-step explanation:
We are to divide the expression
15÷5/7
We can change the sign to a product sign and multiply 15 by reciprocal of 5/7
Reciprocal of 5/7 = 7/5
Multiply with 15
= 15 × 7/5
= 15/5 × 7
= 3 × 7
= 21
Hence the resulting value of the expression is 21
Divide it all by 2rs and the end answer would be 3.
the 4 is in the thousands place so we look at the 6
it is 5 or greater so we round the 4 up to 5
