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
P = 2(L + W)
510 = 2(L + W) ...divide both sides by 2
510/2 = L + W
255 = L + W
3/5(255) = 765/5 = 153 cm <== length
2/5(255) = 510/5 = 102 cm <== width
