The surface area of the spherical ball is given as follows:
yd².
<h3>What is the surface area of a sphere?</h3>
The surface area of a sphere of radius r is given as follows:
.
In this problem, the diameter is of 25.2 yd, hence the radius is given by:
r = 0.5 x 25.2 yd = 12.6 yd.
Then the surface area in yd² is:
.

Step-by-step explanation:
-6y + y=-30
-5y = -30
y=6
x=-6 ×6= -36
Answer:
6(4+y)
Step-by-step explanation:
sum is adding and times is multiply
Answer:
13x^2 - 7x + 6
Step-by-step explanation:
(9x^2 -7x) - 1(-4x^2 + 6)
(9x^2 -7x) + 4x^2 +6
9x^2 - 7x + 4x^2 + 6
(9x^2 + 4x^2) - 7x + 6
13x^2 - 7x + 6
No factors are for multiplication and divisors are for division i think
