Question

volume of a right circular cylinder is 1100cm cube and the radius of its base is 5cm find its height and it's curved surface area ​

Answer 1

Answer:

Height = 14 cm

Step-by-step explanation:

1100 = 22/7 * 5^2 * H

H = 7/22 * 25 * 1100

H = 14 cm

2πrh square units

= 2 * 22/7 * 5 * 14

= 440 round ( 439.823 )

✪QUESTION✪:-

volume of a right circular cylinder is 1100cm cube and the radius of its base is 5cm find its height and it's curved surface area

✪GIVEN✪:-

• volume of cylinder = 1100 cm³
• radius = 5cm

✪TO FIND✪:-

• Height
• CSA of cylinder

✪ANSWER✪:-

➥HEIGHT:-

➠volume of the cylinder = 1100cm³

➠$\pi \: {r}^{2} h \: = 1100 {cm}^{3}$

➠$\frac{22}{7} \times {5}^{2} \times h = 1100 {cm}^{3}$

➠$h = \frac{1100 \times 7}{22 \times 5 \times 5}$

➠$\boxed{\sf{h = 14 }}$

➥CSA OF A CYLINDER:-

➠$2\pi \: rh$

➠$2 \times \frac{22}{7} \times 5 \times 14$

➠$2 \times 110 \times 2$

➠$110 \times 4$

➠$\boxed{\sf{440 cm²}}$

◆ ━━━━❪✪❫━━━━ ◆

CYLINDER :-

➠TSA$=2\pi \: rh + 2\pi {r}^{2}$

➠CSA = $2\pi \: rh {cm}^{2}$

➠VOLUME=$\pi {r}^{2} h \: {cm}^{3}$
