Question

the curved surface area of a cylinder is 28 cm is 880 cm^2.find the radius of the base of the cylinder.

Answer 1

Answer:

we know that...

curved surface area of cylinder =2πrh...

height is given=28cm..

Now..

curved surface area =880

2πrh=880

2×22/7×r×28=880

r=5cm

Answer 2

Answer:

• r is : 5cm
• diameter is 10cm

Step-by-step explanation:

$2 \times 22 \div 7 \times r \times 28 = 880$

$176 \times r = 880$

$r = 5cm$
