Answer:
24 cm
Step-by-step explanation:
8^2 + b^2 = 10^2
64 + b^2 = 10
b^2 = -54
b = 6
10 + 8 + 6 = 24
Represent 24 as a sum of two numbers, first number from first die and second number from second die.
24=19+5=18+6=17+7=16+8=14+10=13+11=12+12=11+13=10+14=9+15=8+16=7+17=6+18=5+19=4+20 (the sums 15+9 and 20+4 are absent, because there aren't numbers: 20 on the first die and number 9 on the second die). Totally, you receive 15 different representations of 24.

(here
means that you have 20 possibilities to roll first number or blank face on the first die and 20 possibilities to roll number or blank face on the second die).

Answer:
A. The red cylinder
Step-by-step explanation:
<h2><u>Which cylinder has the greater volume </u></h2><h3><u>volume of a cylinder</u></h3>
formula:
V =
<h3><u>volume of the blue cylinder</u></h3>
V =
=
=18.84956
to 2 dp
volume of the blue cylinder is <u>18.85 </u>
<h3><u>volume of the red cylinder</u></h3>
V =
=
= 37.69911
to 2dp
volume of the red cylinder is 37.70
<h3><u>the cylinder which has the greater volume is : A. The red cylinder</u></h3>
