Step-by-step explanation:
7x + 28 < 84
- 28 -28
7x < 56
÷7 ÷7
x < 8
If it was a negative 7 the arrow would change direction

Answer:
800 sq in
Step-by-step explanation:
There are 6 sides:
2 are 20 x 8, which each have an area of 160
2 are 20 x 10, which each have an area of 200
2 are 10 x 8, which each have an area of 80
(2 x 160) + (2 x 200) + (2 x 80)
880 sq in (assuming all sides are closed and he is painting them all)
Answer:
I. Volume = 301.6 cm³ (to 1d.p)
II. CSA = 188.5 cm² (to 1d.p)
Step-by-step explanation:
<u>Given the following data;</u>
Height, h = 8cm
Radius, r = 6cm
Curved length = 10cm
a. To find the volume of the cone
Where;
- V is the volume of the cone.
- r is the radius of the base of the cone.
- h is the height of the cone.
Substituting into the equation, we have;
<em>Volume = 301.6 cm³</em><em> </em>(to 1d.p)
b. The curved surface area of the cone
Where;
- CSA is the curved surface area of the cone.
- r is the radius of the base of the cone.
- l is the curved length of the cone.
Substituting into the equation, we have;

<em>CSA = 188.5 cm²</em> (to 1d.p)
