There are 160 tablespoons in 5 pints of ice cream. 1 pint of ice cream is 32 so you can multiply 32 * 5=160
The formula for circumference is C = 2<span>πr.
We already know that the radius of the circle is 21 feet, so let's plug that into the equation.
C = 2</span><span>π(21)
Now let's simplify
C = 6.28(21)
C = 131.9
131.9 is your circumference.</span>
Answer:
Step-by-step explanation:
We know that a straight angle is equal to 180°. Therefore, 120°+(a)=180°
We can solve for (a) by subtracting 120 from 180, which is 60.
180-120=60
m∠a+120°=180°
m∠a=60°
We know that the sum of all angles in a triangle is 180°.
Therefore, (a)+60°+(b)=180°
We know that (a) is equal to 60°, so our new equation is:
60°+60°+b=180°
60+60=120
180-120=60
m∠b+60°+60°=180°
m∠b=60°
