10-4=6. can it be like this.
Answer:
The answer is
<h2>36π cubic inches</h2>
Step-by-step explanation:
Volume of a sphere is given by
<h3>

</h3>
where r is the radius
From the question
r = 3 inches
Substitute the value into the above formula and solve for the volume
That's
<h3>

</h3>

Answer:
£22
Step-by-step explanation:
Area to be painted
4walls - door
a = 4(2.6 * 3.5) - 2.2 * 0.8
a = 34.64 m²
Paint needed
p = 34.64 / 8
p = 4.33
Must round up
p = 5 liters
Tins needed
t = 5/2
t = 2.5
must round up
t = 3
Cost
since 1 is free with 2 will pay for 2
c = 11 * 2
c = 22

Answer: 18.7
Step-by-step explanation:
Find the lengths of AB, BC, and CA
AB =
= 5
≈ 7.1
BC =
= 5
≈ 7.1
CA =
= 2
≈ 4.5
7.1 + 7.1 + 4.5 = 18.7
