Step-by-step explanation:
cuz to sides are the exact same then one side is bigger than the others :)
An arc is a part of the circumference of a circle and the angles that subtend the arcs are proportional to the length of the arc.
So, you basically have two arcs to compare: a 10cm arc and a 60cm arc. But the 60cm arc also happens to be the circumference in this case, so you know that the angle that subtends that arc is 360 degrees (the whole circle). The 10cm arc is 1/6 of the whole circumference so the angle is going to be 1/6 of 360 degrees, which is <span>60 degrees.</span>
The answer is:
____________________________
5.778 mi/ h;
→ or; write as: 5 ⁷/₉ mph {"miles per hour"}.
______________________________________
Explanation:
_____________________________________
We shall solve in miles ("mi.") per hour ("h"); denoted as "mi / h" ; or sometimes, "mph".
______________________________________
Given 26 mi / 4.5 h ; we want to solve for the number of miles (mi) per unit hour (h),
________________________________
The answer is (26/ 4.5) mi / h l
______________________________
26 ÷ 4.5 = 5.7777777777777778→ Round to: 5.778 mi/ h;
→ or; write as: 5 ⁷/₉ mi /h

Answer:
320 ft² (nearest whole number)
Step-by-step explanation:
Given:
- height of fence post = 8 ft
- diameter of fence post = 1 ft ⇒ radius = 0.5 ft
- total number of posts = 12
- π = 3.14
Surface area of a cylinder = 2πr² + 2πrh
⇒ SA of one fence post = 2 · 3.14 · 0.5² + 2 · 3.14 · 0.5 · 8
= 1.57 + 25.12
= 26.69 ft²
As there are 12 fence posts,
Total paint needed = 12 × 26.69
= 320.28 ft²
= 320 ft² (nearest whole number)
