formula for area of a circle: pi*r^2
r = 8, so 8^2 = 64.
64*pi is roughly 201.06
So the area would be about 201.06 cm^2
Answer:
the answer is below
Step-by-step explanation:
0.013089
You would divide 75 by 50 and get 1.5
Answer: See explanation
Step-by-step explanation:
The constant multiple of liters in a jug to the weight in kilograms will be:
7 kg = 9.7 liters
1 liter = 7/9.7 kg
The number of kilograms a 48.5 liter jug of a sports drink would weigh will be:
= 7/9.7 × 48.5
= 35kg
y = - 7x - 20
the equation of a line in ' slope- intercept form ' is
y = mx + c → (m is the slope and c the y- intercept)
here m = - 7 ⇒ y = - 7x + c
to find c substitute ( - 4 , 8 ) into the equation
8 = 28 + c ⇒ c = 8 - 28 = - 20
y = - 7x - 20 → equation in slope- intercept form
