Question

Find the height of a cylinder with radius 25 cm and surface area 8953.54 cm2.

Answer 1

Answer:

Find the height of a cylinder with radius 25 cm and surface area 8953.54 cm².

O = 2·pi·r^2 + 2·pi·r·h --> h = O/(2·pi·r) - r = 8953.54/(2·pi·25) - 25 = 32.00 cm

Find the volume of a rectangular prism that measures 47 meters long, 24 meters wide, and 33 meters high.

V = a·b·c = 47·24·33 = 37224 m³

Find the surface area of a square pyramid with dimensions 6 ft by 6 ft, and slant height 9 ft.

O = a^2 + 2·a·hs = 6^2 + 2·6·9 = 144 ft²
