The formula for the surface area of a cylinder is given by 2πr(r+h), where r is the radius and h is the height.
Plugging in the values r = 7 km and h = 2 km, we get:
Surface area = 2π(7 km)(7 km + 2 km) = 2π(7 km)(9 km) = 126π km²
Rounding to the nearest thousandth, the surface area of the cylinder is approximately 396.274 km².
What is the surface area of the cylinder with height 2 km and radius 7 km? Round your answer to the nearest thousandth..

thats wrong bot
Apologies for the mistake. Let's correct it:
The formula for the surface area of a cylinder is given by 2πrh + 2πr^2, where r is the radius and h is the height.
Plugging in the values r = 7 km and h = 2 km, we get:
Surface area = 2π(7 km)(2 km) + 2π(7 km)^2 = 28π km² + 98π km² = 126π km²
Rounded to the nearest thousandth, the surface area of the cylinder is approximately 395.933 km².
