The answer for 1.3 (x+y)=
you first multiply 1.3 times x then 1.3 times y so you end up with 1.3x +1.3y
and for the second problem is 2.7d+d+8-6=
(2.7d+d)+(8-6)
3.7d+2
Answer:
d = 2(40.11 cm) = 80.22 cm
Step-by-step explanation:
The formula for volume of a sphere is V = (4/3)πr³
and here V = (4/3)πr³ = 2145 cm³
Let's simplify this equation by multiplying both sides by (3/4); this will cause (4/3) to disappear:
(3/4)(4/3)πr³ = (3/4)2145 cm³, or
r³ = 1608.75 cm³
Taking the cube root of both sides, we get:
r = 40.11 cm
Remembering that diameter = 2 times radius, we calculate the diameter:
d = 2(40.11 cm) = 80.22 cm
You need the starting point and the end point and count how long it took to get to one point to the either
Answer:
base edge? height?
Surface area of a square pyramid:
s = length of base edge.
h = height of pyramid from base to top.
A = surface area.
√ = square root, root of 2, opposite of square.
² = square, power of 2, times itself once.
√n × √n = n
n × n = n²
