Mathematics
1 answer:
Tcecarenko [31]3 years ago
6 0

Answer:

2 1/28

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(3/4×7/7)+(9/7×4/4)=?

Complete the multiplication and the equation becomes

21/28+36/28=?

The two fractions now have like denominators so you can add the numerators.

Then:

21+36/28=57/28=2 1/28

What's the lateral area of a right cylinder if the radius of the base is 12mm and the altitude of the cylinder is 5 times the ba
gizmo_the_mogwai [7]

Answer:

1440π squared mm.


Step-by-step explanation:

Given is the radius of base of cylinder, r = 12mm.

The altitude is five times the base radius, h = 5 times 12mm = 60mm.

The lateral area of the cylinder is the curved surface area of the cylinder.

The formula for curved surface area of cylinder is as follows:-

Curved Surface Area = Circumference of base x altitude of cylinder.

SA = 2πrh = 2π•12•60 = 1440π sq. mm.

Hence, Lateral area of cylinder is 1440π squared mm.
