Question

a cylinder has radius 7 cm and height 14 cm.fins its lateral surface area and find total surface area​

Answer 1

Answer:

Step-by-step explanation:

radius = 7cm

height = 14 cm

lateral surface area = 2πrl = 2× 3.14 × 14

= 87.92 cm^2 approx

total surface area = 2πr(h+r) = 2× 3.14(14+7) = 131.88 cm^2 approx

Answer 2

→Question: A cylinder has radius 7 cm and height 14 cm.fins its lateral surface area and find total surface area​.

⇒Given:

• Radius = 7cm
• Height = 14cm

⇒To find:

• Lateral surface area
• Total surface area

⇔Solution:

• L.S.A = 2πrh = 2ײ²⁄₇×7×14
• L.S.A=616cm²

⇔

• T.S.A.= 2πr(h+r) = 2ײ²⁄₇×7 (14+7)
• T.S.A=2ײ²⁄₇×7×21
• T.S.A=2×22×21
• T.S.A=924cm²

∴LATERAL SURFACE AREA AND TOTAL SURFACE AREA ARE 616cm² and 924cm².
