Answer:
This can't really be factored, but it can be expanded slightly.
(3x³)³ = 27x⁹
Answer:
48cm
Step-by-step explanation:
V= L x W x H
V= 8 x 3 x 2= 48cm
It's irrational, number and intiger
Answer:
2) Right angles always equal 90°
3) m∠F = 90° and m∠G = 90° which means they have the same angle measure.
4) Removing the m and replacing with the congruent symbol.
I'm not too sure how this goes but it should be something like that.
Answer:
Surface area = 663π in².
Volume = (676/3)π in² ≈ 225.33 π in²
Explanation:
1) We know the radius and the lateral area.
2) With the radius you can find the areas of the top and the bottom.
For that, you use the formula:
area of the top = area of the bottom = π r²
∴ π (13 in)² = 169π in² (each)
3) Then, the surface area is the sum of the lateral area and the two bases (top and bottom)
surface area = lateral area + bottom area + top area = 325π in² + 2×169π in² = 663π in².
3) You can also find the height of the cylinder.
Use the formula: lateral area = 2π r h
∴ h = lateral area / [2 π r]
⇒ h = 325 π / [ 2π (13) ] = 12.5 in
4) With the height you can find the volume.
Use the formula: V = (4/3) π r³
∴ V = (4/3) π (13 in)³ = (676/3)π in² ≈ 225.33 π in²
