Answer:
168pi cm2
Explanation:
SA = 2pi(r^2) + 2pi(r)h
diameter is 8 cm so radius is 4 cm
SA = 2pi(4^2) + 2pi(4)17
SA = 32pi + 136pi
SA = 168pi cm2
I believe the answer is -2, 7
Solution:
<u>Note that:</u>
<u>Using cross multiplication:</u>
- (3x)/20 = (4x + 2)/28
- => (3x) × 28 = (4x + 2) × 20
<u>Simplifying both sides:</u>
<u>Subtracting 80x both sides:</u>
- 84x = 80x + 40
- => 84x - 80x = 80x + 40 - 80x
<u>Simplify the LHS:</u>
- => 84x - 80x = 40
- => 4x = 40
- => x = 10
Given Kruger National Park in Skukuza coordinate : (-24.98,31.58).
Nelson Mandela Musuem in Mpumalanga coordinate : (-29.82,31.58).
We need to find exactly in between given coordinates.
We know, mid - point formula :


.
.
Therefore, will be meeting at (-27.4, 31.58).
