18cm (A). Remember to get the radius when you have the circumference is to ALWAYS divide it by 2. 36/2 = 18
All you would do is divide 9.99/15 to get how much one pound costs.
The answer would be around 66 or 67 cents.
9.99/15=.666
Answer:
8.77777777778
Step-by-step explanation:
1 boy can work about 0.3 hours
i think that’s the answer,but good luck
We know that
area of a circle=pi*r²
turn A
r=3 units------> 3*(1/10)----> 0.3 miles
area of a circle=3.142*0.3²-----> 0.28278 miles²
by proportion
0.28278/360°=A/90°------> A=90*0.28278/360------> A=0.0707 miles²
the answer is
0.0707 miles²
