Answer asap will give

Step-by-step explanation:

firstly,

V= πr²h

where, r=3.75 and h=6.21 inches=15.77cm

we have,

V=πr²h

=22/7×3.75×15.77

=185.66cm³

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
