Answer:
1759.52cm^3
Step-by-step explanation:
Given data
Cylinder E
h = 30 cm and
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*30
V= 3.142*16*30
V=1508.16 cm^3
Cylinder F
h=5 cm
r = 4 cm
The expression for the volume is
V= πr^2h
V= 3.142*4^2*5
V= 3.142*16*5
V=251.36 cm^3
Hence the total volume is
=251.36+1508.16
= 1759.52cm^3
Step-by-step explanation:
complete the number line
If you would like to calculate (a^3 - 2 * a^2) - (3 * a^2 - 4 * a^3), you can do this using the following steps:
(a^3 - 2 * a^2) - (3 * a^2 - 4 * a^3) = a^3 - 2 * a^2 - 3 * a^2 + 4 * a^3 = 5 * a^3 - 5 * a^2
The correct result would be 5 * a^3 - 5 * a^2.
Answer:
Step-by-step explanation:
BASE + 3x = 22.85.....................equation 1
BASE + 10x = 40..........................equation 2
BASE = 40 - 10x
NOW SUBSTITUTE (40-10x) FOR BASE IN THE FIRST EQUATION
40 - 10x + 3x = 22.85
-7x = 22.85 - 40
-7x = -17.15
x = -17.15/-7
x = $2.45 IS THE PRICE FOR EACH POUND.
BASE + 10 x 2.45=40
BASE + 24.50=40
BASE = 40-24.50
BASE = 15.50 IS THE BASE PRICE FOR THE DELIVERY.
PROOF
15.50+3*2.45=22.85
15.50+7.35=22.85
22.85=22.85
