Answer:
333 in^3
Step-by-step explanation:
Circumference = pi *d
27 = pi*d
Replacing d with 2*r ( 2 times the radius)
27 = pi * 2 * r
Divide each side by 2
27/2 = pi *r
13.5 = pi *r
Divide by pi
13.5/ pi = r
We want to find the volume of a sphere
V = 4/3 pi * r^3
V = 4/3 pi (13.5/pi)^3
= 4/3 pi * (13.5)^3 / (pi^3)
4/3 pi/pi^3 * (13.5)^3
4/3 * 1/ pi^2 *2460.375
3280.5 / pi^2
Let pi be approximated by 3.14
380.5/(3.14)^2

Answer:
Scenario 1: Cameron works at a local grocery store after school. He is paid $8 for each hour(h) he works. And ammount of money can be (m)
considering theres no like first hour pay or something then it would be
Equation: m = 8h
Scenario 2: At a local bakery, one box of doughnuts(b) costs $5(c). Two boxes of doughnuts cost $10.
Equation: c = 5b where b is the ammount of doughnut boxes and c is the cost
<em>Scenario 1a: </em>Jim goes to the gym for 10 hours(h) It costed him $20(c) for those 10 hours.
Equation: c = 2h
<em>Scenario 1b:</em><em> </em>Kayla goes to a for a ride on her bike and traveled 15 miles(m) and was out for 30 minutes. (t)
Equation: t = 2m
Step-by-step explanation:
given :
A=5x - 10
B = 3x
C= 2x - 10
solution:
A+B+C = 180°
5x - 10 + 3x+ 2x - 10 = 180
10x -20 = 180
10x = 200
x = 20
A = 5(20)-10 = 100-10 = 90°
B = 3x = 3(20) = 60°
C = 2x-10 =2(20)-10 =40-10 = 30°
this is the right triangle and scalene triangle
