Step-by-step explanation:
The volume of a cylinder can be found with the equation
<em><u>
</u></em>
So, plug in the values. The diameter of the circle is 10m, which means that the radius is 5m. The height of the cylinder is 13m.
V = π (5)^2 (13)
<u>V = 325π m^3</u>
Answer:
D. 325π m^3
Simplify 3/5p tp 3p/5
4 + 2p = 10(3p/5 - 2)
Expand
4 + 2p = 6p - 20
Subtract 2p from both sides
4 = 6p - 20 - 2p
Simplify 6p - 20 - 2p to 4p - 20
4 = 4p - 20
Add 20 to both sides
4 + 20 = 4p
Simplify 4 + 20 tp 24
24 = 4p
Divide both sides by 4
24/4 = p
Simplify 24/4 to 6
6 = p
Switch sides
<u>p = 6</u>

Answer:
Step-by-step explanation:
This will form a hollow circular part of a cylinder of outer radius 7cm and inner radius 3cm
Area of a circle is given by πr^2.
Then, the big circle of radius 7cm
Area= πr^2
Area=22/7×7×7
Area =154cm^2.
Area of the circle of radius 3cm
Area= πr^2
Area=22/7×3×3
Area =28.286cm^2.
Area of the shaded part becomes
Big area - small area
154-28.286
Area of shaded part = 125.7143cm^2
Then to the nearest hundredth
Area of shaded part =125.71cm^2
