It would be x= -4/7......
The volume of the cylinder is 254,571.43cm³.
The surface area of the cylinder is 22,628.57 cm².
<h3>What is the volume of the cylinder?</h3>
A cylinder is a three-dimensional object. It is a prism with a circular base.
Volume of a cylinder =πr²h
- π = 22/7
- r = radius = diameter / 2 = 60/2 = 30cm
22/7 x (30²) x 90 = 254,571.43cm³
Surface area = 2πrh + 2πr²
(2 x 22/7 x 30 x 90) + (2 x 22/7 x 30²)
16, 971.43 + 5657.14 = 22,628.57 cm²

Answer:
im quite confused with the way its been layed out
cant tell if ur multiplying of its a X
Step-by-step explanation:
(2^8 times 5 ^-8 times 1) ^-2x times 5^-2 over 2^3 times 4 times 2 ^28
(2^-16x times 5^10x times 5^-2 over 8 times 4 times 2^28
2^16=28 times 5 ^10x

Answer:
1350
units²
Step-by-step explanation:
The regular hexagon consists of 6 equiangular triangles
The area (A) of a equilateral triangle is calculated as
A = 
( s is the side length )
Here s = 30 , then
A = 
= 
= 225 units²
Thus the area of the regular hexagon is
area = 6 × 225
= 1350 units² ← exact value
≈ 2338.3 units² ( to 1 dec. place )
Answer:
0.25
Step-by-step explanation:
Prime outcomes on a die: 2,3,5
P(prime) = 3/6 = 1/2
Even outcom: 2,4,6
P(even) = 3/6 = 1/2
P(prime & even)
= P(prime) × P(even)
= ½ × ½
= ¼ or 0.25
