The C of the bowl is 43.98 because C can be calculated like, C=pi×d
And pi is about 3.14, and 3.14×14 is about 43.98
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
Answer:
s=40
Step-by-step explanation:
Combine s and 1/2.
150−s/2=120+1/4s
Combine 1/4and s.
150−s/2=120+s/4
Move all terms containing s to the left side of the equation.
150−3s/4=120
Move all terms not containing s to the right side of the equation.
−3s/4=−30
Multiply both sides of the equation by −4/3.
−4/3 x (−3s/4)=−4/3 x−30 => S=40
Fist you see her goal is 384 you have to divide 384 by 30
