calculet the volume and total surface area of aright circular cylinder of height 1m and radius 70cm.
Answered by Damon
radius = 0.70 meters = r
height = 1 meter = h

vol = pi r^2 h

area = 2 pi r^2 + 2 pi r h

V=0.49pay m^3,AT=2.8pay m^2
Answered by Rakeb Yonas
AT= 2×pay×r×h + 2×pay×r²
AT= 2×pay×0.7m×1m + 2×pay×8m²
AT = 1.4pay m² + 0.98pay m²
AT = 2.38pay m²
V = pay×r²×h
V = pay×(0.7m)²×1m
V = 0.49pay m³

Calculate the volume and total surface area of a right circular cylinder of height 1 m and radius 70 cm find your question with stap?
Answered by Bot
From the given data, we have:

Radius (r) = 3.5 m

Depth of well (h) = 40 m

Volume of earth dug out = 0.49 pay m³

Area of platform formed = 28 m × 22 m

We need to find the height of the platform.

Let's begin by finding the volume of earth dug out:

Volume of earth = pay × r² × h

Substituting the given values, we get:

Volume of earth = pay × (3.5 m)² × 40 m

Volume of earth = 1540 pay m³

Now, we know that the earth dug out is evenly spread to form a platform of dimensions 28 m × 22 m. This means that the height of the platform is the same everywhere.

So, to find the height of the platform, we can divide the volume of earth by the area of the platform:

Height of platform = Volume of earth / Area of platform

Substituting the given values, we get:

Height of platform = (1540 pay m³) / (28 m × 22 m)

Height of platform = 5 pay m

Therefore, the height of the platform is 5 meters.

The given data is:

Height of the cylinder (h) = 1 m

Radius of the cylinder (r) = 70 cm = 0.7 m

We need to find the volume and total surface area of the cylinder.

The formula for the volume of a right circular cylinder is:

Volume of cylinder = pi × r² × h

Substituting the given values, we get:

Volume of cylinder = pi × (0.7 m)² × 1 m

Volume of cylinder = 0.49 pi m³

Therefore, the volume of the cylinder is 0.49 pi cubic meters.

The formula for the total surface area of a right circular cylinder is:

Total surface area of cylinder = 2 × pi × r² + 2 × pi × r × h

Substituting the given values, we get:

Total surface area of cylinder = 2 × pi × (0.7 m)² + 2 × pi × 0.7 m × 1 m

Total surface area of cylinder = 1.54 pi m² + 1.4 pi m²

Total surface area of cylinder = 2.94 pi m²

Therefore, the total surface area of the cylinder is 2.94 pi square meters.

Note: If you need to provide your solution with steps, make sure to include the formulas used and substitute the given values before simplifying the expression. Also, use appropriate units (e.g. cubic meters for volume and square meters for surface area) in your final answer.
