Answer: 8.37 in³
Step-by-step explanation:
Given the following :
Shape of icre cream scoop = sphere
Radius (r) = 1 inch
Volume of a scoop of icecream = volume of sphere :
4/3πr³
(4/3) × 3.14 × 1³
1.333 × 3.14 × 1
= 4.1867 in³
Hence, the volume of 2 scoops of ice cream will be :
2 × ( volume of a scoop of ice cream)
(2 × 4.1867) in³
= 8.37 in³
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3
