Answer:
4 cm radius
- Volume = 267
- Surface area = 201
___
Square root 3
- Volume = 22
- Surface area = 38
Step-by-step explanation:
4/3 * 3.14 * r^3 is formula. For this, I am going to use 3.14 for pi.
Since r = 4, r ^3 = 64.
Now we do 64 * 3.14 * 4/3 = ~ 267.
Now let's do the surface area.
4 * 3.14 * r^2 is the formula. For this, I am going to use 3.14 for pi.
Since r = 4, r ^ 2 = 16.
4 * 16 * 3.14 = ~ 201
______
Now, let's do Square root of three.
3 square root of 3(i cubed it) * 4/3 * 3.14 = ~ 22
For surface area it is 3 * 4 * 3.14 = ~ 38.
:) This took a while xD
The volume is 1017.88

Answer:
l = 14 inches , b = 6 inches
Step-by-step explanation:
multiply length l and breadth b by the scale factor , then
new length = × 35 = 2 × 7 = 14 inches
new breadth = × 15 = 2 × 3 = 6 imches
For this case we must find an expression equivalent to:
To express in scientific notation we must take into account that the power will be positive, that is, the decimal is run to the right.
We test each option.
Option A:
If we run the decimal 9 spaces to the left we have:
Option B:
We discard it because the exponent is negative.
Option C:
We run the decimal 6 spaces to the right
Option D:
We run the decimal 9 spaces to the right
Answer:
Option D
