Find the total surface area of a cylinder with a height of 7 cm and radius of 3 cm. Leave your answer in terms of π.
140π cm2
91π cm2
60π cm2
51π cm2

=60π cm2

Step-by-step explanation:

Total surface area of a cylinder is calculated by 2πrh+2πr2, where π is a constant, h is the height= 7cm and r is radius= 3cm

Slot the values into the formula:

2π(3 × 7 ) + 2π (3)^2

2 π 21 + 2π9multiply 2 by 21, and 2 by 9

42π + 18π

=60π cm2

I hope this helps.

Option C.60π cm2 is the correct answer for this .

Step-by-step explanation:

30, 60, 90

Step-by-step explanation:

since there are 6 x's in total, and there are a total of 180 degrees in any triangle, we do 180/6= 30

so now we know x=30, 2x=60, and 3x=90
