Problem 5
d = 29 = diameter
r = d/2 = 29/2 = 14.5 = radius
SA = surface area of sphere
SA = 4*pi*r^2
SA = 4*pi*(14.5)^2
SA = 841pi
SA = 841*3.14
SA = 2,640.74 square inches
To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.
2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft
<h3>Answer:
18.3 square feet (approximate)</h3>
=====================================
Problem 6
d = 10.7 = diameter
r = d/2 = 10.7/2 = 5.35 = radius
L = 22.3 = slant height
SA = surface area of the cone
SA = pi*r^2 + pi*r*L
SA = pi*(5.35)^2 + pi*5.35*22.3
SA = 147.9275pi
SA = 147.9275*3.14
SA = 464.49235
<h3>Answer:
464.49235 square cm (approximate)</h3>
Answer:
a. 2 x 2 x 2 x 2 b. 2 x 2 x 2 x 2 x 2
Step-by-step explanation:
2 is a prime number so 16 as the product of prime number is 2 x 2 x 2 x 2 and same for 32
In all of that??? Like all parts ??
Answer:
1.429 lbs per sack
Step-by-step explanation:
Given that 10 lbs of flour needs to be divided evenly into 7 sacks
amount of flour in each sack,
= 10 lbs ÷ 7 sacks
= 10/7 lbs per sack
= 1.429 lbs per sack
All sides are the same, hence, all three angles are the same, and each one of them is 60 degrees. Due to that:
7x + 4 = 60
7x = 56
x = 56/7 = 8
8y + 12 = 60
8y = 48
y = 48/8 = 6
