Mathematics
1 answer:
Lapatulllka [165]3 years ago
4 0

Answer:

the radius must equal 2

Step-by-step explanation:

A = pi * r^2       C = 2 * pi *r

set them equal

pi * r^2 = 2 * pi *r

divide both sides by pi

r^2 = 2 * r

divide both sides by r

r^2 /r = 2r/r

r = 2

Divide 63 apples into two groups so the ratio is 2 to 1
GalinKa [24]
1) 2x+1x= 63
2) 3x= 63
3) 3x/3= 63/3
4) x= 21
5) 2(21)+1(21)=63
6) 42+21= 63
The 2 groups would be 42 to 21.

Derek’s bike has a mass of 12 kg and he is riding at a velocity of 8 m/s. What is the kinetic energy of the bike
Marrrta [24]
Answer: The kinetic energy of Derek's bike is 384.

To find the kinetic energy of an object, we need to know the mass and the velocity of the object. Both of those are already given in the problem. So we can simply use the formula.

The formula for kinetic energy is KE  =0.5(m)v^2. All we need to do is input the know variables and evaluate.

KE = 0.5 (12) (8^2)
KE = 0.5(12)(64)
KE = 384
