The surface area of a cylinder is define by the formula S.A.=2πrh+2<span>πr^2, where the first part of the formula refers to the lateral area, perimeter, or circumference and the second part to the area of the bases, which are circles.
On this exercise it is asked to find the lateral area of a cylinder whose radius is 6 cm, and has a height of 20cm. To find the lateral area of the cylinder you should substitute this values into the formula, S.A.=2</span>πrh, and as can be seen the answers are given in terms of <span>π or pi.
S.A.=2</span><span>πrh
S.A.=2</span><span>π(6cm)(20cm)
S.A.=2</span><span>π(120cm)
S.A.=240</span>π cm^2
The lateral area of the cylinder is 240<span>π cm^2 or in other words letter B from the given choices.</span>
Answer:
2n^2 - 11
steep by steep explanation
=(4n^2 + 3n -5) -(2n^2 + 3n +6)
= 4n^2 +3n -5 - 2n^2 - 3n -6
= 2n^ - 11
3/5 = 60%
20 ÷ 5 = 4
3 x 4 = 12
Answer is A) 12/20
Answer:
slope = 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 7)
m = 
= 
= 2
Answer:
He would need 58 yards of material.
Step-by-step explanation:
If there are 4 sets of pillows and comfoters, that means there are 8 pillows and 4 comfoters.
If each pillow uses 0.75 yards of material, 8x0.75= 6
If each comfoters uses 13 yards of material, 4x13= 52
6+52= 58 yards of material.
