The total surface area of a right cylinder which has a base diameter of 10 cm and a height of 7 cm is:
tresset_1 [31]

Answer:

377 square centimeters

Step-by-step explanation:

Formula: h(2×pi×radius) I know there's a second part but I'm doing this first.

First find the radius, in the problem it says a diameter of 10cm

Divide 10 by 2 to find the radius = 5

I'm going to use 3.14 as Pi

7(2×3.14×5)

7(31.4) = 219.8

Next part, solving for the 2 circles

Formula: 2×pi×radius²

2×3.14×5²

solve 5² first (5×5) = 25

2×3.14×25 is 157

add 219.8 and 157 = 376.8 round to 377

Answer: 377 square centimeters

attashe74 [19]

The first column has 10 cubes.

The question states that the other two columns each have 4 fewer cubes than the first column.

10 - 4 = 6

This means that each of the other 2 columns have 6 cubes each.

Column 1: 10 Cubic units

Column 2: 6 Cubic units

Column 3: 6 Cubic units

10 + 6 + 6 = 22

Anna’s Figure has 22 Cubic Units
